People of any race can be Muslim. When someone says "Christians are all crazy" do we say that they're racist towards white people just because the majority of Christians are white?

So then why is it that when someone implies that Muslims are all crazy we assume that that is racism at work?

And it's not exactly a random thing to bring up. Rapture is supposedly going to apply to Christians so even if it did happen, theoretically the Muslims would be left behind, and so in the context of the comic posted that says all the religious wackos are gone, he's pointing out that they wouldn't all be gone.

I'm lost on what is racist about this. Could you please explain?

What has Islam got to do with Race? I'm just saying that getting rid of Christians won't make the earth into an atheist haven. Islam will logically take it's place as it's the second biggest religion.

The hell has this got to do with race???

We are hused to him. He's a well known prat.
