Sure, they're leaders in different disciplines which seem to overlap in the zeitgeist. I doubt Zizek would be able to match Peterson when discussing practical psychiatry.

IMHO, after a brief fascination I've found my enthusiasm for Zizek fading. He seems to know his quotes very well and spits them out like a rapper on speed, but as a career philosopher and author I haven't seen his work leading to positive change in people. Peterson on the other hand has a growing cohort of I regret to say 'followers' who are purportedly cleaning up their acts.

IMHO the group (and subsequently the ideology) is the wrong level of analysis to diagnose and then treat our contemporary woes. Groups cannot be addressed simultainously, cannot be held accountable, and most of all are never clearly delineated (what is 'race'?). The individual CAN be held accountable, that's how every law system on Earth is engineered. The individual can be addressed. That's how almost every communication system in the world works (except public PAs, radio, and the like). And most of all individuals are trivial to delineate. An individual human is unlike anything else in the universe except other humans and each has their own unique history.
