I don't care what other people believe or so long as:
1- It doesn't hurt other people. Ie, "I believe in beating my wife!!!!"
2- They don't desire to change me.
So if you believe the world is flat... that's fine.* I may think you are an idiot for doing so, but I don't care if that is what you truly believe. (*So long as this belief doesn't affect something else... Ie, I am a Geology student trying to get into a PhD program, and you are a flat earth society member who is a tenured professor at the school of my choice. )
If you don't believe in God... that is fine. Just don't knock the fact that I believe in God.
