Previously, they claimed they stand with nazi solely for free speech of everyone purposes, not because they would share the oppressive authoritarian ideology of nazi.
If that was true, that is why.
Now in reality, that was not true, they stood with nazi cause they themselves are nazi who want to bully others.
You keep using the term Nazi but I don't think you actually know what it means.
I can gauge how much of an authoritarian you are with one simple question, is it immoral to privately own the means of production?
