Facebook — Discrimination against Hindus in their community standard

Hi,
I want to complaint about the Facebook having encouraging the discrimination of Hindu through their community standard.

One person has written that "Hindus are Cow urine drinker and cow dung eaters". And Facebook didn't find it as discrimination of Hindu religion by that person comments.

But when I replied like "You are a Pig urine and dung eaters" the Facebook immediately warning me that I have gone against their community standard. So I have understood that if someone wants to discriminate Hindus they are encouraged by this social media gaint. I feel I am discriminated by Facebook. I want to file complaint against Facebook
