Some good comments. Even respectful. Cool.
I do not equate legal with moral or wise. They can be the same, but often are not. Many legal actions are "bad", while many illegals actions are not.
As to watching shows not harming children: Once Hitler controlled the media, (many of) the children raised watching, reading, hearing, learning his message grew up to willingly participate in the horrors on Nazi Germany. IMO, that is much worse that falling off a motorcycle.
As to caring, it is bold to suggest that minding one's own business is tantamount to being uncaring. I thought that should have been clear in my first post, but apparently it was not. Many laws have been proposed and enacted in the name of caring that only served to restrict legitamate freedoms. Every one of us every day "endangers" ourself as well as others. Merely having running water and electricity in our homes is a risk. Driving a car, we endanger a huge number of people almost every time we get on a city street or highway. Same with bikes, perhaps more danger to ourself and less to others than a car, but the same principle is effective. The world seems to have plenty of caring people who want to take away our cars, motorcycles, knives, guns, trampolines, lawn darts, bb guns, etc.
If you really care, should you have cps take your neighbor's kids away if he buys a trampoline? No, being caring and being a busybody are not the same thing.
Again, teach correct principles and let people govern themselves.
