how is alt right different from just the right or the general GOP? I still have no idea wtf alt right is
Alt-right is a lot of people who looked at how ridiculous the accusations of racism and sexism had gotten, thought to themselves, "if everything I say is going to be called racist, then why care what I say?"
If everything is X then nothing is X being the principle. So they started riling people up with racist or inflammatory memes. This then attracted actual racists and fringe groups who joined in. It's 4chan acting like Stormfront for lels which then attracted Stormfront.
So you have people with no sincerity at the core surrounded by fringe people who are sincere about some dumb things. (Like nRX, which no longer believe in democracy and want some philosopher King/CEO of the nation.)
