Am i biased?

I grew up in Europe and mostly Christian. I say mostly because I'm not really religious personally. But i have observed that most Christians are chill people and not so fanatically religious. Even of they are, they just keep it to themselves and their family. In my country there are a lot of Muslims. I have observed that they are kinda more agressive and blunt. And if i try to talk to them about religion they get defensive and possibly insult me. My boyfriend is Muslim. And he says that if we had kids he would want them to be Muslim. So that they can stay away from cigarettes, alcohol, sex etc. I grew up with no religion essentially because i wasn't really interested in religion and i was taught all this stuff without a religion. Meanwhile he has smoked and drank and i didn't do any of that before him. The reason i didn't have a problem with religion is because it's not that important for me. Thoughts?
