What to do when your son is a racist?

I saw that question recently. I have the answer: beat them yourself.

Update: Two minutes after I first made this post, I already got several annoying emails. I simply want to clarify that after you are done beating them, you should beat yourself for teaching them such hate. Thank you.

Update 2: You people are way too sensitive. Seriously there is no justifiable reason for blind hatred in the modern era. You have a child with blind hatred? They deserve a just punishment. The reason you should be conducting the beating is because instead of having his/her hatred reinforced by having the beating come from those they incite to defensive violence, you should show them the equal evil in your own (insert false barrier here).
