Along the lines of the “Yes, You’re Probably Racist” twitter feed (or is it a website?), I think we need a Primer for Halloween for people who seem developmentally challenged in entering the 21st century. So, is it cool to dress up for Halloween in black face? No, not cool. Is it cool to dress your child up as a member of the Ku Klux Klan? No, that’s not cool anymore. Not sure when it was cool.
