If you want to criticize someone's philosophy, you need better arguments then ad-hominem.
I wouldn't call him a philosopher, because philosophy to me must have a timeless element that is necessarily detached from any specific time or society, and Jordan is first of all a clinical psychologist, which makes his experience inherently tied to the current society through his practice with patients.
That being said, we are living in the current day, I think his lectures and books are very helpful for anyone struggling with the meaninglessness of modern life.
I also personally dislike his usage of Christian mythology and ethics in presenting the "how-to" of life. It might be useful as a narrative tool, but Christianity in itself is extremely toxic life-denying philosophy.
Hmmm, you lost me there. Are you talking about the politics and practices of current American evangelical right wing Christians? I'd agree with you there.
But in light of how Peterson digests Christianity I'd say it's the exact opposite of your claim. "Pick up your damn cross." and "Clean your room." as exemplars of such.
Furthermore, Christianity offers hope and redemption through faith in Jesus Christ, rather than promoting guilt. Sin refers to actions or thoughts that go against God's will, which can harm individuals and society. However, forgiveness and transformation are possible through faith in Jesus Christ.
Romans 3:23-24
> Christianity offers hope and redemption
Hope and redemption is only necessary if you think all humans are guilty by being alive and therefore hopeless.
