I think that researchers, educators, and others with power over institutions & culture publicly lampooning and attacking anyone with even the thought of daring to ask a 'dumb' question or have a 'dumb' theory, without proper rite of passage and standing as a crackpot has a larger negative effect than whatever positive effect these attacks have in dissuading (probably not!) the delusional and fraudulent from stuffing people's mailboxes with their theories and amassing followings.

Political thinking that probably predates the Egyptian pyramids: If you empower people with freedom, it will be abused in a way that produces some suffering for everyone that wouldn't be had the freedom not been granted. There would definitely be tradeoffs to having a culture of free and open learning, research, and knowledge sharing, unguarded by institutions.
