It is simple. When a person working for a company makes vile statements to a national audience, and the company decides to air the tape, and the company’s reps (Jay Leno and producers) do nothing to stop or even tone down the vile statements, then said company is giving direct support of the bigoted trash. It makes no difference if during other events the company was a bit more favorable.
If RW had said something truly horrible and deeply offensive about women, or minorities (think Imus here), Jay Leno and NBC would never have allowed it to air, or they would have at the very least cleaned it up for airing. Yet, the subject of RW’s perverse and sick humor was the Church and the faith, so it was considered okay to air the entire skit. That is anti-Catholocism in action, and NC/Jay Leno and RW are guilt of it.
