"That seems a gracious concession from you"
I've always believed this. Racism is not a political issue is a human issue. All races have people who are racist against others. All political parties have racists.
I may not have been clear in the past because the left wants to paint EVERYONE is does not march 100% in lock step with them as the worst of the worst. And I have been trying to tell you that anyone who thinks like that is out of their minds. They are not living in the real world.
"Then why do neo-Nazis hate communists and liberals?"
I don't know. Perhaps you should ask them. Why did the Italian socialists execute Mussolini? Why did the German socialists hate the Nazis and vice versa? Stalin called Mussolini a right winger and he meant that as an insult, a serious insult, like if someone used the "N" word or how the left and the right calls each others Nazis.
"Ask 100 neo-Nazis if they identify as socialists or support socialism. How many do you think will say yes?"
All of them. If they answer, no, then they are idiots and are just hanging out with them because the hate Jews and blacks.
"That's absurd and stupid. Neo-Nazis don't all hate capitalism, and SJWs fight AGAINST them."
That is your opinion. In the 1920's, at the height of the Progressive era, (when the American left openly and publically embraced Nazism) the American Nazi Party published a newsletter entitled "Social Justice". Social justice has always meant the same thing. It is about justice for the "oppressed". All socialists, the ones who actually know what socialism is, all hate capitalism.
"And even more people on the extreme right"
Opinion, not fact.
"And you don't have to even go that far on the right."
Not true. The further right you go the more freedom minded and the smaller to no government minded people are. They really don't care what anyone else does regardless of race because it is none of their business. These are libertarians and anarchists (not social anarchists - those people are what Stalin called "useful idiots"). A true anarchist does not want to collapse one type of government and replace it with another. They don't want ANY government.
So I go back to a previous statement, racism is not a political issue. However, there seems to be a lot of Antisemitism showing up on the left in the past 10 or 15 years. Of course it is your side who is telling everyone that blacks are too stupid to get a voter ID. So there's that.
