To some degree. I suppose it's an exaggerated version of muh Autism Level. I mean obviously a guy with no legs is never going to run faster than Usain Bolt or someone with mild retardation is never going to be a scientist or whatever, but that doesn't mean they shouldn't get a comfortable life and the ability to do something they're good at. Otherwise most of this site would be killed off, seeing as most posters are fat autists.
That said calling someone stupid or blind shouldn't be a banable offense. The degree to whoch a certain socialist comment board bans is insane and is probably a big reason why the alt-right surged, because a few fuckwits decided it's better to screech instead of educate the ignorant on a subject that's been obfuscated by porky propoganda for decades.
