So why are certain weapons and explosives illegal? What if I want to have all kinds of that stuff? I'm not harming anyone. I am less harmful than a school bus driver who's been smoking pot all weekend.
Certain weapons are illegal or hard to obtain because, just as with some drugs, the Feds want to have control over our lives and having access to military-grade weapons and explosives would endanger their noble aims of controlling our lives and protecting us from ourselves AND from the boogeyman du jour.
I neither want nor need such “protection.” As a grown and responsible adult American, I am fully capable of making such decisions myself... which is another reason I abhor the war on some drugs AND those who champion it. I chose not to use such drugs, but it is MY PLACE to make that choice. It is NOT YOURS TO MAKE IT FOR ME. Is that clear enough?
