nothing wrong w/ making fun of retards, queers or catholics or any other group so long as everyone under the sun gets the same treatment - like the drill instructor from full metal jacket says - here you are all equally worthless
that said, making fun of folks for the deliberate purpose of hurting them is lame, more so if they're incapable of defending themselves - but if we're to treat all folks equally, then either no one gets fucked w/, or everyone does - the trick is in the balance, in being the cheeky-fun-loving-asshole, not-the-fuck-your-sister-in-her-cornhole-and-tell-everyone-on-the-playground-about-it kind
