I don't think it's a misrepresentation at all, especially if you consider the anti-Fa movement. anti-Fa is ironically using very fascist tactics in their protest of fascism.
That's what I was thinking when I said "beware of the news bias". Regardless of what one thinks of specific actions of the Antifa movement, it's not necessarily true that those represent even Antifa members as a whole, and it's completely specious to assume they represent anarchists as a whole. Antifa is not even an anarchist-only movement.
