This seems fairly straight forward to me, but I don't think of any of my friends or relatives as racists, so I can't imagine it being tough or even questionable. "If you have a racist friend, now is the time for that friendship to end." It seems easy, it might take conviction beyond the comfort level for some, but if you don't have that you might as well throw in the towel. I mean, c'mon. There's no excuse. Post the video below on your wall and then unfriend them. Baby steps. Or go big at Thanksgiving. Make a scene n' shit. All joking aside, you really don't need toxic shit in your life. You won't ever be able to totally avoid it, but that doesn't mean you have to hang around with it.
