The alt-right feeds off this. They want to be called racist, xenophobic, etc., because they believe that society has applied these terms too aggressively to folks who weren't actually racist or xenophobic ("the boy who called wolf"). There's a lot of anger stemming from that, which leads to behavior that's hard to understand for many people. They're not trolls, but there is an element of trolling in what they do.
