I was a Hindu for 23 years of my life. I agree that it is relatively a peaceful culture, of course except for outliers (extremists), but ultimately is about believing in some kind of god(s). Such a belief has potential to be harmful irrespective of the name of the religion

Is she trying to recruit you or is she simply sharing to you for the sake of talking to someone she confides in, maybe there are other reasons. I get it i so get it about anger at religion. The initials of Belief System are BS. it's my idea though that everyone who has one isn't necessarily out to convert people. Maybe there's an agenda maybe there isn't Have you talked this over with her?

Every religion is peaceful if it is so small that there is no chance to take power OR if is so big that no other can question its power.
If there are 2 or more competing religions all goes to hell.
The only region where this happens with Hinduism is on the north of Indian sub-continent.

I must emphasize here that Hinduism is not a religion. It is way of life. You can still be a Hindu even if you do not believe in God, unlike other religions in which you have believe in God who established that particular religion. So you can join Hinduism and still be non-believer.

Well, you have this caste system directly related to hinduism, and that sounds pretty bad to me. It's great if you are in the top caste, but really shitty if you are in the untouchable caste. Kind of like capitalism, but with different fables. If you think it's not as harmful as other religions, ask someone at the bottom of the heap what he or she thinks of that claim.

I know that IamNot from India..... That's what I know
