Woodrow Wilson was arguably the first fascist president and presented a model that was later copied by the likes of Mussolini and Hitler. There were other American presidents that also were affiliated with such things, but what made Wilson unique was the shear size of the second KKK. Something like 20 percent of eligible american men were members.
Should the proudboys and related grow into something comparable to that than fascism is a real concern, but fortunately we have a very long way to go to until the right wing is better organized like this. This past summer has showed the left is more organized than otherwise thought.
What's your explanation for how the dude allowed the KKK to grow and how he leveraged them to advance some of his political goals?
