That is a continual process in our legal system with many laws, but the one driving force is what I said above. As time passes, the Conservative far right, is moving more to the left. Not just in our laws, but our entire culture.
Times are not the same as they use to be in many many laws, and in trends of our culture. Things like dress codes disappeared, which is a good reflexion on the way times have changed. Examples: My Dad was an engineer, and went to work everyday in a suit, white shirt, and tie. Now engineers go to work in bluejeans. People use to dress up for dinner out, or other events. Men would wear suits, women would were dresses, even to sporting events. Films of old boxing matches or baseball games,all the men dressed in suits. Kids would wear appropriate nice school cloths, slacks and collared shirts to school and church. In the east, when I was a kid, that was required, but when I came to california, kids could wear bluejeans and tee shirts. Now, kids can even wear Now shorts. Tee shirts/shorts are Normal cloths for eating at what used to require Men to wear a jacket and tie, to very expensive restraunts. Manners, proper edicate, and table manners, are gone. times have changed to much more lax, and acceptable, a lack of standards is prevailing in every part of our culture.
