You need to straighten out your definition of fascist. Hitler is a fascist. Take your favorite definition of fascist, like Ecco's or whatever, and Hitler will satisfy it. He does fascism. His policies are militaristic, nationalistic, he enacts laws to suppress minorities, etc. Someone who votes for Hitler does none of those things, but they're still a fascist by any sensible meaning of the word.

Today, there are fascists operating in our democratic systems. From the British National Party to Trump. Not all of them are actively overthrowing the systems they exist in. One such fascist is Tommy Robinson. DHH has expressed explicit support for Robinson and his white nationalist rallies.

You do not know DHH's politics. You don't know who he voted for. Nor do I. But we can make an educated guess based on his open white nationalism and his explicit support for fascists. If someone basically tells you "hi, I'm a fascist", you believe them.

Also, I don't know who you think you're helping by playing these semantic games (based on shoddy definitions btw).
