First off, it's good you finally raised this topic on meta. Instead of trying to "bring attention" to my "biased" posts on the main site, wish you had come to meta sooner so that regular users here could properly address or respond to your concerns.
Are we allowed to quote a random article or person who has an opinion about our scriptures or mentions that something exists in our scriptures?
Absolutely. For example, see this excellent question: K.S. Bhagavan's critique of Adi Shankara
No one asked Who the heck is K. S. Bhagavan? nor questioned the religious inclination of OP. Instead the focus was on what is being asked and users decided to respond to it in an answer. This is what civilized discussion looks like.
Before people jump on my use of the word 'random', here is a statement from @sv himself in one of his questions:
P.S I'm looking for well-researched answers, not copy-paste answers from random blogs.
There is a huge difference between quoting a random blog in a question versus an answer. A claim can originate from anywhere including a random blog but using the same blog in support of an answer is not encouraged as we want to avoid the copy-paste issue. My note at the end of that question was about random blogs in answers.
Are we allowed to ask for reference/justification without doing any basic research about the topic or the bias of that person?
It's recommended but not required. If one has time for research they can do it. And in the process, some people discover the answer themselves and may still ask the question in "an honest innocent" manner and then go ahead and write an answer themselves for the benefit of others. If the person OP is quoting is biased, the answer gives you an opportunity to expose the bias.
For example, my question was closed as 'primarily opinion based'...
I voted to close it as 'too broad' and not opinion-based. I found this part of the question too broad:
Which books & verses in those books is he referring to here?
Also, both the above and this line below:
Are there any scriptures which he might unknowingly be referring to?
...sound like mocking the author and my other questions involving him than real questions. Now if your question really was:
Do our scriptures simply acknowledge the existence of 3rd gender, or do they also wholeheartedly accept them acting upon their desires?
Then that should have been the title and it can be objectively answered. But then you revealed your real intent behind these questions:
I don't really have these doubts, this is only to bring attention to discuss what is opinion-based question or not.... – ram 2 days ago
I'm sure these questions will be deleted in a couple of days, but I want to draw attention to other users too, not just mods. If sv can bombard the site by referring to random articles and YouTube videos (just go through his list of questions), and claim that he is simply being 'factual', so can others, and it trashes the site quality. – ram 2 days ago
So what is your actual complaint about one question getting closed? Shouldn't you be happy the other two questions of similar nature still remain open? If you had a problem with my questions you should've come to meta to discuss/complain instead of asking more questions to mock my questions or the site rules.
In the past, I had a problem with Where is xyz's śastra/weapon now? type of questions, but I didn't ask more such questions to "bring attention." Instead I came to meta and asked How to answer questions about the status of divine weapons? and left it at that. Just because you dislike someone's questions or their style of asking, doesn't mean you make a tamasha of it on the main site and incite other users into downvoting and closing valid objective questions. Multiple users including a mod have already explained to you in comments in layman terms how my recent questions were valid and not opinion-based. But you just don't give up.
This has led me to report the constant harassment on my recent posts to the site owners:
Lately, most of my posts, old and new are being serial-downvoted. One particular user is also constantly harassing me in comments. I have flagged some of those comments and were promptly deleted by the mods. But this behavior needs to stop. Mods need to ensure the discussion in comments remains civil. Action should be taken against repeat offenders.
This is the response I received from them:
We have several automated systems in place to prevent malicious or targeted voting. These will generally revoke inappropriate votes within 24 hours. "Inappropriate" means someone going through your profile and down-voting (or up-voting) the posts they find without regard to their actual content. For more details, see: What is serial voting and how does it affect me?
At your request, an employee has been assigned to review the history of votes directed at your account. If they find any evidence of malicious or targeted voting, they will take appropriate action to correct the problem. However, we are not able to provide details of that review and you will not receive further responses about this issue. If this pattern continues for several days, contact us again and we'll review the situation again at that time.
Some of his questions are outright inciteful, knowing fully well shastras say one thing, he is asking for 'logical proof' to the opposite thing.
What's the problem with asking for logical proof? Someone already answered it logically and I even accepted the answer. As for my post being "inciteful", no one had downvoted my question until the recent downvote. Anyway, if you must, I suggest you express any "displeasure" arising out of your mind reading abilities via downvote. If you were paying any attention, @Rickross gave the same advice to you:
I can see that you have problems with Devdutt Pattanaik and this question but for that you can downvote the question (which I think you have already done) and move on. As I have said this is quite clearly not close-able (at least not as opinion-based). @ram – Rickross 2 days ago
We can not really check hidden agendas as we are not mind readers. So, we have to see each question and decide. We can not also put a complete ban on a type of questions here which can be answered from scriptures and the discussion adds to the readers knowledge. BTW I don't have much knowledge about the author and his works but if you really think that he misinterprets scriptures and misleads his readers then questions like these give opportunity for others to expose him. But that is possible only if we answer them. So your intent should be answering them as opposed to closing them. I don't think they are opinion based. – Rickross 20 hours ago
Lastly, I would also advice you against mocking or alienating Devdutt Pattanaik for his sexual orientation or Zakir Naik for being a Muslim as you have attempted to do so in some of your recent posts and comments. The new SE Code of Conduct has a zero-tolerance policy towards bigotry:
We don’t tolerate any language likely to offend or alienate people based on race, gender, sexual orientation, or religion — and those are just a few examples. When in doubt, just don’t.
We take your reports seriously. Those who don't follow the Code of Conduct in good faith may face repercussions deemed appropriate by our moderation team.
