"Race realism" is just a meaningless label Neo-Nazis use, because they are still trying to fly under the radar, or they are slightly embarrassed of being what their grand-parents fought. They might try to butter up their standing by (falsely) citing stuff like the Bell Curve, but it is still the same vile and evil ideology it was 80 years ago.

But not all fascists are neo-nazis. Just because a subset of today's fascists describe themselves that way, doesn't mean they are fundamentally different from other fascists. Look at Steven Miller; he's jewish, and quite obviously a white supremacist. He's all about dehumanizing people he thinks of as leser, and he welcomes the new fascist America. AfD, the german far-right party, is both very pro-Israel and loves to play "tread the nazi line and extend it"-game. Anti-semitism is a common, but not necessary prerequesite to fascism.

When I was younger I also thought the opposite of good should be bad, and it is silly to describe things as evil. I disliked the religious connotation, but have changed my mind. There are people committing absolutely horrible things, and calling it anything but evil is underestimating the depravity of those characters. To quote Captain G. M. Gilbert:

“In my work with the defendants (at the Nuremberg Trails 1945-1949) I was searching for the nature of evil and I now think I have come close to defining it. A lack of empathy. It’s the one characteristic that connects all the defendants, a genuine incapacity to feel with their fellow men. Evil, I think, is the absence of empathy.”
