I am unbeliever. Not an atheist, just unbeliever. Why? Maybe because I grew up in USSR. Though, I'm bapthised in Russian Orthodox church. It was "in fashion" during a first post-soviet years - to revive religion. Mother brought icons and religios books to home. First, it was interesting - to read those books and to learn prayers. That time I was about 10-11 y.o. But later I was bored of it. Implicit faith just didn't come.
And now, I thing to myself that this is good - I haven't any veil on my eyes. I'm not belong to any religion, so I can respect all of them. And I don't have to call to kill either muslims or christians or buddhists or someone else...
