Bob, I think they'll become relics, not from repressive governments over time but more from changing attitudes over time, as communities got away over time from chewing tobacco and spittoons---or nearly. I live on a 15 km country road and there's not a soul who would shoot a rabbit, grouse or deer to save their lives. They see it as spitting tobacco, a filthy and disgusting habit. You're right, media does shape our culture. Makes it great for unapologetic dinosaurs like me!
