Nothing says, man I have a super low social IQ, and probably a low IQ period, than proudly displaying racism and asking people around you, "What's wrong with being a total racist asshole?" then wondering why the people around you don't want to be there any longer and think you are lower than whale poop (and we all know whale poop sinks to the bottom of the ocean)...
Stacking human poop in your yard has about the same effect on your neighbors and those around you as openly racist sentiment.
Hide it in the closet where it belongs, it is shameful stupidity and deserves nothing better than mockery.
That you would be *shocked* that some idiot who can't think to remove racist paraphernalia from his walls when selling his house might get fired from his public servant role is just more evidence that you can't actually understand that other people think differently and think that racism is something that should be hidden like being gay used to be. Just hide your ugly sin. Nothing would make us happier.
