I don't know if I'd say that all Halloween dummies are racist. (although the Maines family sounds like they are! Haha!)
Anyway...I think a dummy with a black hood, in light of recent news events, might be seen as racist. And when people take offense and ask you to remove it, a civilized person would say, "So sorry, I didn't mean it that way. Just thought it was a good Halloween scare, and never thought about the color of the hood or Jena or the other recent noose incidents. My apologies." Take it down and buy a scarecrow and some pumpkins and mums like normal people so you can be on the copycat neighbor thread.
What sounds racist to me is to get all up in arms over something you CLAIM is an innocent Halloween decoration, and start talking about what "THEY" say and what "THEY" do to take away your rights to put up tacky crap in your yard in honor of Halloween. "Slippery slope" and "pretty soon we won't be able to say Merry Christmas" and "letting the terrorists win" and all that garbage. For Pete's sake, it's enough to make you appreciate your homeowners association.
GMAFB. It's Halloween. The noose is upsetting to some people. Who cares why? A good neighbor would take it down. An ignorant redneck starts humming Dixie and telling you that you can have his Halloween dummy when you pry the rope from his cold dead hands.
Why can't we all just get along?
