The song has not been banned. A specific radio station decided to stop playing it (remove it from their playlist) after many of their listeners asked them to.
As a supplier of music, they listened to their customers and stopped providing a product that they're costomers didn't want.
As to claiming the double standard, since we don't know the complainers, we have no way of knowing what their taste in music is. Also, most profane rap music isn't masquerading as a romantic duet (context).
I'm actually surprised it took this long for it to become an issue at all. I'm fairly conservative and do think people take things too litterally, and I've been jokingly calling it "The Christmas date rape song" for several years now. If I saw that in it, I'm surprised it took this long for "screeching feminist" to make it into an issue.
