Someone made a fool of you about Cow and Indian relation. Here in India HINDU respect and workship because Cow is a form of a God in Hindu culture. Don't make joke on any culture. If you respect yours than respect others.
It's believed that cows are people who've died, reincarnated, and their new life is as a cow. Where'd you hear that? One of our deities is a cow (another FORM is, there are multiple forms) but. cows ≠ people man.
