I come to your offerings for my daily chuckles!
Is pot illegal? Is beer illegal? Which users do you think would be on the business end of a gun to obtain either one? Which dealers do you think carry guns. I have never seen one of my beer distributor's drivers packin' heat when they deliver their product. I have never heard of a liquor driver getting into a shoot-out with police over their cargo.
Your right when you say it one's own choice to do either one when they are 21. Most who care to imbibe or smoke pot do it long before then.
I do however agree with your point about the drinking age. If your old enough to fight, and possibly die for your country, you should be able to drink in the country that you are fighting for! Pot is another question.
I look forward to the day when you realize the errors of your thinking on the present situation with our gov't. It will come sure as I'm typing this. Hopefully I'm here to see it.
