That's not my country and not much of my business but if half of your country is fine using its free speech defending KKK apologists and the other half only meets that with apathy, don't be surprised if some Black Panthers come back to life and use their own free speech fighting back.
And maybe I am less shocked by this affair because in many European cities, wearing a MAGA hat would be seen pretty close as wearing nazi insignia. Under it, lies either someone very racist or someone very confused. And either way probably someone that is not going to have a constructive participation.
So yeah, probably lack of clear rules, lack of due process, I hope that's the takeaway they'll get from it.
Arbitrary enforcement of vague rules is authoritarianism, but you can have clear rules and due process to limit hate speech. It has been done successfully in several places.
