Yeah, I heard that. You hear a lot of things, but I think as a rule this wasn't a pervasive opinion of my generation. We weren't all long-hair drugged out hippies marching in the streets.
Kids in general still had respect for older people- you still heard some say "yes sir" and "thankyou". Maybe not like in previous generations because things were changing- but today's kids would laugh at the idea of doing that.
