Ben Shapiro acts respectfully when answering students and debating BLM or other persons. I've seen so many instances of bad behavior on the part of his conversation partner, yet Ben remains cool and professional. The worst I remember is that instance where he refused to use a pronoun on Television. If I recall the trans person in that situation behaved very badly.

Jordan Peterson remains cool, even with interviewers that treat him badly.

Dave Rubin says repeatedly he's willing to talk to people, and that people refuse him and don't invite him.

Tim Pool keeps his cool in the midst of online and real-world dust-ups.

Tarl Warwick is also calm cool and collected. He'll talk to anyone.

Any leftist who wants to engage others productively can look to Pool as a good example.

Jimmy Dore is on the left (according to himself at least), and he's civil.

My impression is that most anyone on the spectrum will talk to anyone else, except for Resisters, who seem to have a visceral dislike for Trump that clouds their reason; and the far left, who object more or less to the entire western way of life, or capitalism, or something that would require a large amount of dismantling. It takes a lot of dissatisfaction to want to start from scratch, and these persons seem to be the most badly behaved. So my guess is they feel most of the contempt and also are the ones who receive the most contempt -- because of their abusive behavior. In fact, if the far left has any lasting principle at all it would appear to be that contempt is a wonderful club to use against anyone who isn't responding properly to their dogma.
