Why would you not also much rather vote to eliminate the financial burden being placed on me by drug use, rather than trying to keep (some) drugs illegal?
I would vote to keep the financial burden placed on you, only because you support it's legalization. But I doubt that piece of legislation would pass constitutional muster.
Now, if you're asking if I'd much rather vote to eliminate the financial burden being placed on me by drug use, then the answer is yes I would.
Why can't I do that, yet keep those drugs illegal? Why must I also vote to make them legal?
Let me summarize. I would be more inclined to hear your argument for drug legalization if I didn't have to support the drug user. Not that I would necessarily agree with legalization, but I would be more receptive to hearing about all the positive effects of across the board drug legalization.
