Islam is maybe not a race but it's how it's considered. Muslims are counted not by their faith but by their origins. The migrants are considered Muslims as long as they come from Muslim countries.
There's evidence against what you're asserting. Poland offered to take some Christian refugees. Of course, Western European leaders took this offer as evidence of double plus ungood wrongthink.
If Merkel really thought that taking in Muslims is only positive, she should be happy to take more Muslims and let Poland take care of the Christian refugees. But Merkel's real interest is forcing her will on countries like Poland. It's what German leaders do. They can't help it.

For myself, I'd be OK with Canada taking in a reasonable number of Atheist refugees from the Middle East. (Those wishing to leave Islam need refugee status more than anyone!) I think Canada would be improved if a lot of Ayaan Hirsi Alis were added to the mix. The problem is if you take Ayaan Hirsi Ali and Muslims, the Muslims murder Hirsi Ali. And that's the choice governments make when they import Muslims. Because everyone knows they will murder the Hirsi Alis. They tell you they'll do it. And then they do it.
And, I assure you, I have at least as big a problem with "native" Westerners who convert to Islam as I do with non-Western Muslims. I can have a little more sympathy for people who are Muslim because of the culture they were born into. I assume some of them are thoughtful enough to realize their religion is dangerous bullshit, but having realized that they also know the most dangerous thing they could do is openly reject it.
I don't understand the link between the sentence you quoted and your claim...
