Respect is most important thing we should maintain in posts and comments. But in some cases it is "subjective" to decide whether post or comment is offensive or not.

Hinduism Stack Exchange is a question and answer site for followers of the Hindu religion and those interested in learning more about Hinduism.

So, anyone who are interested in Hinduism besides native followers can join this community. At the same time users should respect core values or philosophy of Hinduism (on which all Hindus unanimously agree). One can't ridicule Gods (Devas) or Rishis who heard Vedas. If a user wants to know Scientific proof of Hindu concepts such as rebirth, divine nature of Vedas or if he/she involves Sceptic thinking with help of Modern Science, then this community is not for him/her. A fellow user shouldn't ridicule beliefs of Hinduism (although many such beliefs can be proved with logic which was done by Hindu philosophers in past, but that's different thing).

If you see any post or comment which you feel offensive, check whether OP is newbie or some experienced user. If newbie, he could have made incidental statements. Check his activity and if many users (say 3 or more users) feel offended, flag his posts for moderator attention. If experienced users makes such comments, flag their comments or posts as rude. It's always better if you mention the reason using "other" flag. Flag comments which are offensive to many users.

Coming to your question, from traditional Hindu perspective this comment can be bit offensive (although opinions vary depending on users knowledge and belief in principles of Hinduism). It's always better not to post against something on which all Hindus agree unanimously. Apart from core philosophy, there are many paths and Sampradayas in Sanatana Dharma. "Constructive Criticism" of one philosophy by others through "Sastra Charcha" (scriptural debates), as per rules laid down in Sastras (scriptures), was/is very common in Hinduism. Let's only give place for Constructive Criticism and that too only if really needed.

We should also remember this site is to learn Hinduism not to debunk Hinduism, before we post any questions or answers or comments.
