Re: as if we were the only country on earth with such a problem
Heard of the term "Red Fascist"? When an organisation uses Fascistic tactics in the name of their cause, then they fit the bill.
Antifa are generally seen as being the modern equivalent of the Brown Shirts, so pretty nasty.
I could create a death squad and call it the "Pink Fluffy Unicorn Love Team", and it wouldn't alter what they actually do.
