When did being a moron become comedy?

Bruno, Borat, Will ferral, Steve O, etc etc. How is this ever considered funny or comical. Lenny bruce, Bill hicks, George Carlin, Comedy that was Sharp, intelligent, Witty this is true comedy. Being a fall down retard "ferral" that thinks its funny to insult or troops, staple your yourself to yourself "Steve O", Slap around your parents "bamm" These are disgusting. base, no talent hacks that have no Real ability or brains. Does anyone else find this a insulting as i do?
