All three books - Old Testament, the Bible, and the Quran contain plenty of passages that would fit your description of hateful rhetoric. But that's not the concern here at all. The question is why is a small group of hatemongers objecting to a peaceful practice that has been going on without incident for decades? 

As for the problems in Europe, you may be unaware of some basic facts - the income, civic engagement, and educational levels between North American Muslims and European Muslims are vastly different. There's also plenty of violent, naked racism in Europe that is creating those problems. 

I'm not downplaying anything. I'm a Canadian-born and raised Muslim citizen. I'm educated, I pay my taxes, I run my own business. I went to high school in Peel region in the mid-1990s and attended Friday prayers without incident. I'm familiar with Muslim socio-economic issues all around the world. I can confidently and definitively counter your ignorance any day of the week.
