Seru, the speed limit is a restriction of freedom. The founding fathers believed in a restriction of some freedoms to maximize life, liberty, and the pursuit of happiness. Every law is a restriction to freedom and I am grateful for those restrictions that help me to lead a more full life. I am dumbfounded that you don't mind toxic waste being dumped into the environment as long is it is not your backyard? On the contrary, I would guess that you are against other countries having "weapons of mass destruction"?
You may enjoy reading up on food chains, biology and the like if this kind of thing interests you. I would guess that you have not looked into it that too much.
Oh, and not everyone on here is American. Canada does not have founding fathers, so we tend not to reference them very often.
