Indeed Tate could have continued spewing whatever toxic garbage online that he wanted to, and continued to scam people with overpriced "courses" a la scam Trump University, if he had not allegedly committed multiple very serious crimes in Romania. Of course he should get whatever fair process that Romania may offer to determine his guilt or innocence, but as so many of us are expats here, he's subject to the Romanian system, not the US or UK one.
He's not being charged by Romania for being a grade A misogynist A hole which of course he is. He's under investigation for extemely serious crimes that will be putting him away if convicted.
