Not sure who this disembodied "they" are, I have yet to see anyone on the anti alcohol and anti tobacco bandwagon who isn't real big in the anti legal weed bandwagon, too. I know it's a wacky idea totally devoid of the required hypocrisy and desire force others to live the way you want them to live, but if you want to stop the anti alcohol and anti tobacco nazis, you may find allies in the pro legal weed crowd.
I see plenty of pot advocates on FR who are antialcohol and antitobacco.
