I don't know who Jack Chick is, so it's a reference that's lost on me. As as the community ethos mentions, we welcome people pointing out oppressive behavior, just not personal insults. Certainly pointing out that someone appears to be disconnected from reality isn't a direct insult like calling someone a dick, asshole or similar would be.
In all honesty, speaking personally and not necessarily as a mod, in the community I favor discussing comics over discussing comic creators themselves (although obviously there's some crossover). I like to see enthusiasm for comics in the community and less so criticism of creators over their works, even in cases it might seem justifiable.
