Guns, fast foods, and tobacco are legal. If the "gooberment" wanted to exercise total control it would make them illegal, just like drugs.
But why should they be made illegal? People use them responsibly, don't they? Certainly the people don't use tobacco then sue somebody else because "they're not responsible" for becoming ill? They wouldn't eat fast foods, then try to sue the fast food suppliers for their weight gain, would they? And how can they possibly sue a gun manufacturer and the distributor and the pawn shop, and the uncle for a murder by the nephew who stole the gun?
We live in a society just like the one that existed in 1776, don't we? You know, the society with no safety net, where people took personal responsibility for their actions. When people had morals and you didn't have to have "sexual harassment" laws because men wouldn't dream of treating a lady that way. And when women were ladies, not sluts cranking out 8 different children by 8 different "fathers" and demanding that I pay for them.
I'll make you a deal. You give me the moral, responsible society that we had back in 1776, and I'll vote for any drug law you want.
