I dont discriminate at all. Prejudge, yes. We all do. When i see a white dude in a camo hat, jeans and boots i assume he is a hillbilly. I dont hate arabs but black folks dont blow shit up. White boys shoot schools up.
Al Nursra... (African arm of Islamic terrorism, aligned with IS)
You must be fairly sheltered if you are never around muslims who are normal. They make up around 1/6th of the world's population; majority here do not wear full garb, many doctors are muslims and I have debated some who took the piss about the whole issue (he said dying to fuck 72 virgins would be a bloody mess).
I dislike people who don't culturally assimilate AT ALL. Ie no attempt at learning language, respecting laws, interacting with locals - especially if it means openly opposing culture of country YOU moved to.
