So when I hear Jordan Peterson say he's being oppressed by the evil forces of Marxist postmodernism for being asked to use preferred pronouns...But you've never heard that. You've only heard him reject being coerced to do that. He's even on the record as saying he's fine with addressing people as they'd like to be addressed, so long as it's all done civilly. What you're doing is projecting a caricatured position onto him.
For my own part, a lot of my frustration is the loud and sincerely meant (if wrongheaded) declarations of victimhood by the privileged, simply for being asked to be nice to others.
A law that empowers kangaroo courts isn't "simply asking nice." A law that empowers those courts to use an unscientific "unconscious bias" test that claims to get into your head isn't "simply asking nice." A law that can result in dismissal from your job isn't "simply asking nice."
I hear a comfortable, privileged person complaining about how he's a victim.
He doesn't claim he's a victim. What he claims is that the law is a potential abridgement of freedom. You could make a claim that Lindsey Shepherd claims to be a "victim" https://www.youtube.com/watch?v=vpFUvfAvKs4 -- but then you'd be presenting evidence that Dr. Peterson's assertions about the law are correct.
And when he doubles down and says people shouldn't get to choose their own pronouns, their own identity, and instead society should choose for them? Then he's a hypocrite. And an asshole.
A coworker at my work announced her transition, and everyone just started using the feminine pronoun. Everyone was civil about it, and everything was fine. (And I am certain that she was happier and a more vibrant and complete person for making the change.) Again, you are misrepresenting his position. More accurately, a person exists within society (and hopefully a community) and identity is something which is effectively negotiated between the person and society. It's the parties who are being emotionally dishonest, playing games with emotional blackmail, and being crappy people who are "being assholes." From where I'm sitting, it's a lot of emotionally imbalanced trans "activists" who fit that description. Jordan Peterson gets mail from trans people, the majority of whom are supporters or sympathetic to him. Their collective position is that they just want to not be singled out and live their lives in peace.
