We already stepped in it. A number of pundits and public figures have been tweeting (I know, ironic) sentences in substance similar to "Free speech advocates are the promoters of white supremacy and white colonialism", also said equivalent to Jan 6th supporters.

Some proeminent ones have even quit Twitter altogether with that as a message.

I know but I'm pointing out that it's not an inherently invalid assessment of the situation. One can hold it in good faith, so what terminology should they use instead?
