"BP made and operated NONE of those things."

As owner and organizer of the operation, BP is ultimately responsible for oversight of those they hire to design, build & operate the platform. (Just as NASA was responsible for being sure Morton-Thiacol provided safe O-ring seals for the space shuttle)

The supposed 'bigots' have noted the culpability of ALL relevant parties to this disaster. It really doesn't matter whether you 'believe' US congressmen are bigots or not, for even bigots can sometimes see the areas of responsibility in such cases.

There is plenty of blame to go around on this one.
