Indeed. If you watch his interview with Shapiro there was a moment where his true colors come out, but they cut it from the public video and only included it "for the members" on his website. Shapiro (who is very genuine in his faith at least) wants to know if Dersh is as well. So he starts asking him questions about if he is practicing jew, believes in God, etc. Dersh gives classic BS wordshimthy answers that are designed to deceive the listener, trying to say that he is both a good boy practicing jew in the club and at the same time doesn't really believe in God (classic modern atheist jew position). Shapiro being who he is doesn't let him get away with the wishy washy answers and drills down on him like 4 or 5 times. Dersh just flops back and forth super slimy and you can see Shaprio go from giving him the benefit of the doubt to having impression "this guy has snake tongue" written all over his face.
About as least-trustworthy a person as exists.
