I think OP means that people in Europe hate each other for various reasons other than being "white christian" even if a lot of them are that. See how Romanians are treated almost anywhere in Europe, despite a lot of them being as white as they come, and Christian too. See how Poles are still perceived in a lot of places.

So yes, I actually agree with that statement - in Europe white christians will be primary recipients of xenophobia, but it's neither because they are white nor because they are christian.
