If American Idiot was your first cd your a poser

K I know American Idiot came out over three years ago, but I still want to talk about this. I see Icons all the time saying American Idiot wasn't my first cd. There for saying that if you didn't buy any other cd before AI or heard about Green Day before AI then your a poser. But what if you were like, 10 or 12 and you bought AI. You're most likley not gonna have heard of Green Day while you were like 6 unless you had an older brother or sister like me and used to listen to Green Day with them. But really, it shouldn't matter what cd you bought first, aslong as you like the music.
