Many many stupid Beatles songs? What is your basis for that exactly?
Meh, don't take it personally. It's kids hating everything that came before them. When I was growing up I hated the old music my parents listened to...now my kids hate the music I listen to. It's the same thing over and over. Just like the guy said a few posts back "some fuddy duddy old band that no one cares about". It's like he has to say that. It's hardwired into their brains...they can't help it.
Just ignore them. They'll see when they grow up and their kids crap all over the things that they like. It's an endless circle bound to repeat over and over. In the grand scheme of things, it's all pointless anyway.
