"Oh, you mean a democrat?"
Careful - pot is much like booze in its effects. It's not the substance so much as the person who uses the substance that causes problems. Your argument about it not being harmless because some of the people who use it cause harm is the same argument that those who would take our guns away use - we say guns are harmless and it's the person who uses it and they point out that because they can be used for harm makes it wise to confiscate them...
I used to agree with you, but immersion in political "discussions" over the years has taught me the importance of consistency in defining what one stands for. If I agree with one set of actions, the n I have to agree with those that use the exact same principle, even if it entails something that I don't like. Else, I become a cherry-picking enigma that is all over the spectrum and holding to no definable set of principles.
Very articulate post...and excellant use of logic.
