I guess they haven't heard of the 8th commandment ("Thou shalt not bear false witness...") (9th commandment by Protestant count). At a minimum it is irresponsible to rush to judgment without trying to ascertain the truth. Maybe the MAGA caps mean that the students forfeit the right to have their side of the story heard before judgment is passed.
I have seen and heard several leftists state that anyone who voted for or supports Trump does not deserve rights.
Luckily rights don’t come from leftists, and they may have to have that lesson inflicted upon them in a manner that won’t soon be forgotten at some point in the near future.
