Any time is a good time to don't be racist, not just at the holidays.
So my challenge to you is to pick one way to not be racist in the coming year. You write that down on Martin and Luther's King day and try to don't be racist in that way all year (not just a few weeks).
My MLK resolution is to not be racist at Gypsies. Like when they have me pay two bucks for my soda pop with my little ceasar's hot and lonely pizza, I won't say " oh man, what a Gyp!" because even Gypsies and pollacks deserve for you to not be racist at them.
