Calling people who you disagree with “crazy harpies” is demonizing. How about “clueless religious” for vegans even though there is nothing faith based (or clueless) about not liking to see animals slaughtered. Endless ranting is also not mature, adult disagreement.
And none of these speaks to why Peterson gets to lump entire swaths of humanity together, but no-one else does and in fact he has a cow if they do, and yet he does it routinely. The hypocrisy is really unparalleled!
