How about “I’m not a racist but…”

Or: “I don’t have a racist bone in my body.” Wow. Racism is a bone? Does it show up in X-rays or scans? Can it be surgically removed? Is it a painful procedure? Surely it cannot be an essential part of the anatomy as non-racists presumably lack this bone.

I am rather hoping that it is just the one bone as this is already getting way too complicated.
