Yeah when I was young there was this poppy boy band that was really popular in the GTA called B44 (dunno if they were popular anywhere else)
But they had a song that went like
"If you get down on me,
I'll get down on you,
I will do anthing that you want me too
It's a game of give & take to make it through,
If you get down on me,
I'll get down on you tonight."
There's much more than that, but it's obvious what the song is about.
My friends & I LOVED this song and we made up dances to it and were confused when we weren't allowed to do our dance in the school talent show

Not to mention I'm A Slave 4 U, Saturday Night Divas(Another rejected talent show number lol), Lady Marmalade (which is BASICALLY the some thing as If You Seek Amy--kids are saying the same thing, just in a different language

)etc.
Point is, i had NO idea what they were talking about and it didn't hurt me in anyway. It didn't make me skanky or some sort of freakish fiend or whatever. It was just a popular song that I liked.
So I really can't see how If You Seek Amy is hurting anyone.
