I'd rather re-educate Bloomberg than expel him. He is hardly a halfwit -- just has a major blind spot on this particular issue. He has oodles of money that he made by building an extremely profitable business, that has never emitted even the faintest whiff of corruption or book-cooking. He is also an ambitious fellow, and it's probably been clear to him before this incident (which I doubt had anything at all to do with the NRA), that his current stance on guns eliminates him as a possible Presidential candidate -- for either party. I think he honestly believes he's right on this issue, and honest, intelligent people can be reasoned with. Given his competence, visibility, and wealth, I think it would be well worth trying. If he could ever be turned into a "convert", he'd be an unusually effective one.
Yeah, you may well be right. Maybe we ought to get him a round-trip ticket to Vegas and a two-day pistol course in Front Sight, Nevada. Maybe throw in a one day SMG course, too; just to cure the fouled-up thinking about what an "assault weapon" is.
Nothing changes the mind like having your personal experience be different from your wild imagination.
