Jack Chick has a "ministry" where he distributes comic book tracts. The vast, vast majority of them excoriate the Catholic Church. To call them inflammatory is the understatement of the century (go to my profile and scroll down to see a couple of samples). In fact, the current Religion Moderator has banned them from being posted, because they are so inflammatory.
Catholics saying that something is "Jack Chick" is a codeword for conspiracy theory anti-Catholicism...comic book anti-Catholicism.
Just looked at your profile ... looks like Jack-o has got himself a new artist, with some actual talent! Amazing. The paranoid conspiracy theory stuff is worse than ever, though. Let's not forget to pray for those poor, lost souls. Father, forgive them, for they know not what they do.

It's really ugly stuff.
