Too much of anything is always bad. The difficult part is agreeing on the right mix.
As for J Peterson, his ideas are certainly well thought out, and the fact that he has a large following, from all parts of the political spectrum, allows certain people to bring up his large RW following as proof that he is evil/incompetent/opinionated/etc.
He is not just another opinionated guy with a YouTube channel, he is actually a tenured profesor at the University of Toronto in the field of Psychology.
He is not right wing at all, as a matter of fact, his notoriety began when he opposed a law that would have forced Canadians to use people's preferred pronouns, which is totally absurd. In your own fantasy, and sometimes demented mind, you can use any pronoun you wish, but forcing others to do so , and live in your reality is something not even G Orwell considered.
If I should want to be referred to as, "His exalted royal highness", should people be jailed if they don't do so ??
He has no problem complying with requests to use preferred pronouns, and has often done so in interviews and debates; he has a problem with being forced by law to do so.
I suggest getting less information from YouTube.
