In my opinion, everyone has the right to decide whether to believe or not (I believe in God); to what extent each part of religion matches his life views; and what norm to follow (I come from a family that is mainly Eastern Orthodox + some followers of the Catholic faith, yet I only view myself as Eastern Orthodox although in general I respect Catholic people and Protestants). However, I have no problem with agnostics, atheists, or Muslims, as long as they behave normally. If we have other things in common - great. Religion is a topic I rarely discuss in real life and I believe faith is a pretty personal thing. As long as you respect my views, I respect yours - this is my general attitude.
