Roboto, it was in the northern part of Michigan. It was very common in more rural communities. I never had any use for big cities. Full of crime and crap. Same today only worse. Some say it correlates with kids taking drugs for ADD and other things. I think its more complicated and most likely can be traced to several things. When I was growing up we had one or two single family homes and that was the odd man out. Not its more the norm. perversion is also the norm, I have no issue with two people of the same sex but many seem to want to wash their and others kids in it. We did not have video games that made very real looking killing easy. My mother would yell at me to get to bed when she was watching Hitchcock's the birds as it was to violent for me. Now that would be a Sat. morning cartoon. Pre 1941 80 percent of Americans lived on farms. Now its this weird almost machine run corporate farming and every one want to live in a friends city situation or sex in the city BS. When I was growing up it was not easy to get your hands on a playboy, and National Geo. was the best you could do. Even as a young man, to get blue movies you would go to a video shop and get and OK to go in the back room with a curtain to rent one. Now you can see it as it happens on ten thousand channels no questions asked. I don't think the human can adapt to this as fast as technology has changed.
As far as guns go, most liberals do not know the difference between an AR15 and a Browning BAR or Remington 7400. The latter two are hunting rifles in semi auto. The 223 or 5.56 used in most ARs is more anemic than what most would use for hunting medium game like deer. A 3006, 308 is very common and would do 10x the damage of a 223. And the guns work the same way the AR does. Gas operated self loading. This is why the 1994 crime bill failed.
Fienstein lied when she said it worked. ARs were built for the ten years they were supposedly banned. An AR with a flash suppressor removed [does nothing more than help not blind the shooter from flash at night] and the bayonet lug removed made it not an "assault rifle." I bought a Colt Match Target Sportster in 1996 that does not work any different than the pre ban type. So the idea that shootings went down because of the ban is an out and out lie.
