As I tried explaining it to you in the Moderation Chat Room, as long as the citation addresses the question at hand it can be a valid reference for the site.
Rickross: @Pandya Are sources/books like the one used in the above answer valid? I think its time we draw a line.
sv.: I'm just curious. How do you draw this line? On what basis should the sources/books used be disallowed?
If the person saying the same thing is Swami Vivekananda and the book cited is Complete Works of Swami Vivekananda, then it should be allowed? So we should focus on who is saying it and not what is being said?
Why don't you propose this new rule on Meta?
That is what this FAQ says:
In the absence of any scriptural reference, written works of scholars, researchers and popular personalities can be used which must be providing a relevant answer.
It doesn't say, the scholar needs to be Hindu, Indian, initiated (to read, translate and comment on the Vedas), etc. The only requirement is that the answer be relevant to what is being asked.
AFAIK, neither Stack Exchange nor this site currently discriminate authors based on gender, nationality, religion or political affiliations, so we don't keep a whitelist/blacklist of authors and publications.
This isn't the first time this issue has come up. A few users even had problem with answers citing works of modern/controversial gurus:
So if you don't like Iravati Karve and her works, you can downvote answers that cite her all you want. But banning some authors (just like modern gurus) simply because some users don't like their views/conclusions may get SE staff involved in the workings of this site.
We really need to identify people whose work reference can be used to cite sources. We should only allow works of those people who studied scripture as per Dharma like under some Guru's guidance etc. Otherwise answers from these anthropologist will only bring chaos. – TheLittleNaruto 5 hours ago
So all modern translations of Vedas, Upaniṣads, Gītā, etc. especially by Westerners should be disallowed too? Example:
And what about users who provide their own English translation of Sanskrit verses in their answers? Shouldn't they have "studied scripture as per Dharma like under some Guru's guidance"? How do we find out if these users are really qualified to write answers on this site? Even if they self-attest, should we just take their word for it? Maybe we should thoroughly vet all new users for their "Hinduness" before they are allowed to write answers on this site. Seems like a great way to run an SE site.
