My simple point was that many expressions and most jokes are at the expense of some group some jokes are acceptanle some aren't. However many that are, are only because the offended group doesn't complain.
Such jokes are, many times are at the expense of people that are either: fat, dumb, blonde, gay, Irish, Polish, Italian, diabled black, elderly, hillbilly, or George Bush.
Selective indignation is what I have a problem with.
