too much inbreeding?

you know how too much inbreeding in animals can cause health and immune issues? it's also been the reason given for some mental instabilities as well... perhaps we humans could take a cue from this and STOP FUCKING INBREEDING... I mean seriously... we've just about eliminated the ability for some people to have any goddam common sense... and if they do have any, they have no fucking idea how to use it... quit banging your relatives people
