Would black guys not hate as much?

If white guys only dated the big ugly black women? Soon as a black dude sees a fine looking sista on a white guys arm all the sudden its a problem. But most white guys, not all, tend to like the slimmer light skinned women instead of the big nasties. I notice this extensively when I go out with my wife, there seems to be much more tension built up in black guys. But when I go to the store/wherever with my big fat ugly sister-in-law, black guys can care less about us.
