hardly any worse than pure vileness of twitter.

I get that you're being glib, and I'm not fan of twitter... but openly supporting ethnic genocide is a lot worse than anything going on with twitter.

what site do “the nazis” use now? Do they just keep to themselves? or do they use other nazi forums.

chan sites, gab, some forums on tor... I'm honestly not sure if they're trying to hurt conservatives or if the continual embedding into conservative social platforms is an attempt to cling to relevancy?

I don't think all conservatives are nazis by any means, but I'm not a fan of the "any vote we can get" tactics that are hesitant to admonish white supremacy

I think they are fusing, conservatives and racism have almost always been correlated, so there is a common ground.

Having that said, nazism and republican conservatism are surprisingly different, say, nazis are anti jews, conservatives are anti mexicans. Again, there is a common ground.
