As long as they label someone racist, sexist, fascist, Nazi, homophobe, islamaphobe, or generally a bigot, they can terrorize you, torture you, kill you, harass you, hate you, maim you, abuse you and treat you any way they like. It's a free pass to be an enormous piece of shit.
And the neat part is that they can put that label on anyone they want for any reason (accurate or not, and usually not) and somehow still think they're a good person and in the right because of the label. It's like magic. It justifies literally any behavior as long as they maintain cognitive dissonance.
That's the left.
