I'm agnostic, but for me the answer is simple. Let others believe about what they want. That is basic respect about things that can't be proved. Their belief is a valid as yours, since none has been proven.
And since you don't respect other people's beliefs, of course you don't care about what they think. I pointed out that from others perspective, they shouldn't respect you. And yet, many times they do anyway.
In fact, monotheistic religions keep plenty of priviledges. Which is why atheist resorted to create santanism in places like USA.
What I wonder is why Christians decide to go against the bible and don't respect others.
