The problem as I see it is that the rules are not applied evenly: the leftist politically correct comments are never censored regardless of how offensive they are, because they are not offensive to the Medium Administrators who agree with them. Medium doesn’t think calling Conservatives Racist, White Supremacist, Misogynist Nazis is an insult. To them “it feels accurate. It isn’t an insult.” Call a Progressive a “Stupid Socialist” (a lot less offensive) and see how you fare.
I’m glad “Respectful disagreement is possible.” I think you and I would enjoy a conversation over a beer, even though we’d probably never agree on economic or political theory. One example of “Respectful disagreement” is that I don’t see how “stubborn and stupid” isn’t an insult!
