Eric, re-read everything you wrote and replace the word drugs with guns.
Just sayin', YMMV.
Re-read it and substitute anything you want for the word drugs - right to free speach, right to vote, ability to read, right to life, freedom of religion, etc etc. You can play that silly little game all day, but aside from a debate about who is the most hardcore libertarian it means nothing in the real world. You are comparing apples and cinder blocks.
Guns are not addictive (Yes they are like chips, but you know what I mean). They dont cause crime, they dont cause child neglect, they dont impare driving, they dont diminish your health, and I have never heard of a single case of anyone ever sucking a dick to get a gun... Need I go on?
All I am trying to say here, is that you dont want to live in a society where crack, coke, meth etc are legal. It will greatly increase the proportion of the population that uses, and that stuff can quickly turn fine upstanding citizens into crazed crack heads willing to do anything to get their next fix. It would also increase traffic fatalities.
Yes, you can easily make the case that pot should be legal nation wide, but there are not enough people that smoke pot to ever get that to actually happen - or they are too lazy. Its hard to tell. I personally dont think pot should be legal (JMHO) but I would have no problems with making it essentially on par with a traffic violation.
