Rooster, I wasn't being vindictive, I was being satirical.
I fail to see your point about irresponsible people in existance strengthening your argument. I think you might be missing the point of my argument. If an adult desides to be irresponsible, that their choice.
Okay, if a child desides to be irresponsible, I suppose that's their choice as well, but youth view things differently and without the aid of experience. They are naturally drawn to certain things that are potentially harmful to them and they aren't typically mature enough to thing through the consequences beforehand.
And in the case of drugs, by the time the are mature enough, it is often too late. I have plenty of friends who smoke and wish they didn't, but it is very difficult to stop once it becomes an addiction.
And I know that you didn't say that pot wasn't addictive, but there are earlier posts in this thread that have.
Still, I think there is a flaw in your comparison between drugs and gun control. If I have understood you correctly, you were saying that the bad people are going to get the illicit items anyway. Or, at the least, they would find other means. I think that banning firearms would reduce the number of murders of opportunity, but in general, premeditated murder would still happen regardless (as you pointed out) and banning firearms would increase burglary as honest people would have one less way to protect their homes if they are so inclined.
I do see your point and agree that banning the means is not the cure to the problem. However, the argument that it should be legal because bad people are going to do it anyway is fundamentally flawed.
Consider a child growing up in a household where a healthy respect for others is fostered. The child becomes a teen and decides to start rebelling. Hopefully, the child has been taught well, but assuming the worst here, the child is likely to turn to petty theft and possibly drugs as a form of rebellion. Eventually, this might lead to more desperate acts, but for the most part, rebellion is a cry for attention, so it is not likely to progress too quickly.
Now, a different child who grows up in a household where the father is a drunk and the mother is a pot head (for example). What's this child going to do when he wants to rebel? I suppose it's possible he will do so by getting straight A's in school, but more likely, it's going to be far worse than the previous case.
Anyway, I don't discredit the argument, which I feel is valid enough. I just don't agree with the concuclusions that you draw.
