LOL, our "society" "tolerates" the killing of the unborn. And you want to exile drug users? Good luck with that.
Most Americans think that drugs are a problem. So how do you deal with the problem? I think it makes more sense to go after demand than the well organized supply.
The same is true with abortion. Going after abortionists with the law won’t work. We have to convince the people not to go to them in the first place.
