Why is Glen Diesen oscillating between based and reactionary buffoon?

This is a pretty current podcast episode where he invites and supports a jordan peterson like reactionary who spreads disinformation, racism and all out hate against everything he deems "leftist".

I suppose Diesen is a conservative after all which helps with understanding how he could be so reactionary but I thought he otherwise made really apt points (mostly in the rus-uk conflict).

It gives me cognitive dissonance that someone can be so correct on one issue and HUGELY off in another.

How do you deal with situations like this?
