Stuff and nonsense. Rush made fun of no one. He was right to point out that the Democrats constantly use victims to mouth their messages because they want them to be beyond criticism. Ann Coulter had the same message about the 9/11 crowd that politicized their own "victim" status to support Democratic positions. If we are going to just "go along" and let them do that sort of thing without calling them on it then we deserve an electorate of under-educated and over emotional boobs.
This is small fish conservatives who are trying to make a name for themselves.
It does not matter how correct Rush did everything, this small fish would criticise in order to build up his own image.
