I also have a difficult time feeling bad for these privileged fools who are acting as useful idiots for the rise of fascism. It's unfortunate that in all their alienation they haven't developed more class consciousness. Perhaps all their youthful angst and energy could be directed towards productive ends.
I suspect that many have tried and were rebuffed. In undergrad I was rebuffed more than once because 'cis-white men can't be of any value as allies except as audience members and patrons' Which I took to mean 'fuck you, shut up and pay me.' That's an actual quote by the way. I only heard that specific phrasing once, but when I tried to have more serious discussion with people supposedly interested in 'equality' that rhetoric was what I got back.
