Do modern Nazis still say "Heil Hitler!"?

Do modern Nazis still say “Heil Hitler” or have they replaced it with “Heil Trump” or whoever they wish to “Heil” at the present moment?

Yes, to all of the above.

I’ve seen images of Ku Klux Klan doing the salute.

This dude changed his name to Hitler so in the style of The Producers he probably says “Heil myself.” Maybe I’ll ask him the next time I see him. I wish I was kidding about that.
