Well, i was raised as christian, at the middle school(grades from 7 to 9, primary school is 1-6 here, and high school is 10-12(so 6 years primary, 3 middle, 3 high)) i was deist, and now I'm agnostic.
I don't have anything against other religions, until they start being annoying and forcing you to convince to their faith, because our is the best etc. Most people think that religion makes people do good, well result is the same, but which one is better: Someone helping you out of fear of divine punishment, or because he wants to?
Buddhist may be found cruel by someone, because thanks to their belief in karma they wont help anyone poor/starving/troubled, because they think that's punishment for past life/lives, but they are expecting the same from others.
It's kind hard to live in 95% catholic country, where 5% are made of Jehovah wittiness and Jews, and most people see no difference between agnosticism and atheism. Where being baptized is enforced by society and parents. We theoretically have free-religion but just dare to be different... its especially visible in primary school. For agnostic its not so hard, you can tell just that you believe that god might exist, but its very hard for atheists and Jews, it's sad but true that most of people here are antisemitic(but media forbid us to even call them polish version of Jew, and make us call them "Followers of Judaism"), and 33% of my country's people would make Jew-jokes at concentration camps(those left by Nazi Germany).
