Now you just sound like you want to change the world...
(Directed at no one in general)
It's been talked over and over here on ASC. Laws are laws, we don't make them, and we don't attempt to change it here on ASC. We simply just follow and enforce them to the best we can; to protect the game sort of speak.
If you don't like the Laws, you can vote for the City Council, MPPs, and MPs that you like when you're 18. If that doesn't work, move to places where you feel you like the laws or convince your parents to move. If you don't like the 18+ law in Canada, you can move to US, Japan, or wherever they allow underage airsoft.
