Why am I hated by many for being an atheist?

I never express my opinions about this topic unless asked for. I was a hindu, now I am of no religion. I am hated by many for my views like I make my own destiny and God is just an imaginary source of hope. (Keep in mind I said this to them only when they asked.) I don't believe in pooja-path and I've backed my research by finding out that hinduism doesn't force anything. My parents then force me to wear the "sacred" thread of brahmins, later asking me why I don't wear it while saying that its just a normal thread. Is every religion somewhat fucked-up or is it just the people who need a more accepting attitude?
