No, it's not. There are a finite number of .com registrars-- how many of them do you suppose want to be associated with Literal Nazis?
Even if it only serves to waste their time, hassling fascists is still a public service.
There are many privacy/free-speech oriented registrars and hosts. I hate being in the position to defend these types so often from short-sighted moralizers, but it absolutely won't work.
Giving Nazis hell is never a waste of time.
Giving racists, on either the left or the right, is never a waste of time...
I'm not sure what left or right has to do with racism but have an uptick for giving racists hell - but it was kind of implied by the 'Nazis' yo.
