NOT Another Hypocritical Word About Imus People

I heard on talk radio - The Big Talker - today that Villanova had 50 Cent play at an opening basketball game. (It appears it happened last October) 50 cent just so happens is on my boycott list. The question was asked on talk radio how can Villanova now call themselves a supposedly a "Catholic" University and condone 50 cent at the same time.

"Yayo performed and brought out 50 Cent to do "So Seductive." (So Seductive Song Lyrics - Warning: explicit.) Perhaps no group was more animated in its approval than the Wildcats themselves. The usually restrained crew let loose on the court, dancing as 50 Cent performed. Meanwhile, fans strained to get a close-up look at the star. After an invigorating performance, the two performers made a quick exit into a limousine parked behind the Pavilion."

Didn't Imus get his shoes busted for saying some of the same things that is in the lyrics of this song? When 50 Cent says things like this is ok though?
.
Why is that?
.
It's not ok as far as one University - Rutgers - one young woman on the basketball team is filing suit against Imus still - but it is ok with another - Villanova?

Where's the Rev. Al Sharpton as far as this. He had quite a bit to say about Imus.

For the University to condone this is hypocritical.

I'm writing to ask the Catholic League about it.
