fascist group the “Proud Boys” in Portland." Next paragraph: "Proud Boys are against those who protest against hate groups, groups who espouse racial divide and bigoted points of view, hate of women and so on."
By your statements, Antifa fights against those who oppose "hate groups."
Again, you have no idea what you're talking about and you take the position that most mainstream media commentators take: "Well, if they call themselves 'anti-fascists,' then they really must be against fascism." In reality, Antifa exemplifies fascist tactics and beliefs. That doesn't mean that you must then support the Proud Boys just because you loathe Antifa. It's obvious why commentators and leftists assert that you must, though.
