Very provocative comment. But which intelligent human isn’t feeling anger? In USA
Particularly, where we thought Democracy was a real thing.

The fundamental difference is that angry wite males (and females) built a great, modern, amazingly good world. The angry islamists built exactly nothing and do whatever they can to invade the terrible, decadent developed world and convert it into the same Muslim shithole they came from!

One group has so much materially but so little meaning in their lives and the other has the opposite problem.

With all due respect to the working class, a lot of the anger is partially theirs to own. Multple opportunities at retraining has been offered to help families transition in industries that were disappersring.

But most were short sighted. They thought that it would last until they retired, then they wouldn't have to worry anymore as it was somebody else's problem.
