Obviously, I wasn't paying attention..... what's with the "baby it's cold outside" thing? somebody get their undies in a wad?
Without the context of it's time, and examined solely through the lenses of our modern sensibilities and culture, it comes across as very "rapey". The woman is seemingly trying to extricate herself from a pushy man, and he sounds like he's hounding her.
I now have the context to understand that this song is about a woman that wants to stay over, but needs to find a socially acceptable reason to exercise her desire for him.
It's actually quite empowering, but the lack of context turns it into a very different song.
Some easily offended people got really upset when some radio station somewhere, most likely not even in their own listening area, stopped playing the song. Not all that much unlike when people were outraged that anyone would dare criticize or make fun of Rudolph The Rednose Reindeer tv show.
We used to refer to a certain lager popular with women as 'a leg-opener'. There was a very predatory attitude back in the day which was acceptable. It was your job to get sex and her job to stop you. I think this is the big question now: is trying to get a woman drunk so she will be more agreeable to sex the same as spiking a drink or using date-rape drugs?
