This is a dreadful thing to say, but i have wondered in my darker hours that, if everything were legal, wouldn't it be kind of a darwinian solution to a lot of problems? who are the bikies that you see who are cruisin' around with no helmet or with a hat turned around like that yoyo in cheap trick? they're dummies, and if they splatter their brains all over the sidewalk, they're not going to be collecting food stamps.
As more and more people recognize the level of violence involved and the consequences of cte [chronic traumatic encephelopathy, a degenerative brain disorder], they're obviously going to say "we don't want this to be a part of culture." and they overlook the fact that there's a huge swath of the populace where physicality is still a real common thing.
