You don't have to embrace anything in your private life. But stay the heck out of mine.
Yes, but unfortunately all individual choices eventually start bleeding into other peoples' lives, no matter how much you like to pretend they are encapsulated. Otherwise alcohol, tobacco, gambling, and more would only affect their users, but as we know they create collateral damage and rippling effects into their respective communities all the time. Your "private life" booze problem could kill my whole family in a DUI.
Oh, sorry, you were talking about collateral damage caused by people you don't like! My bad.
I don't necessarily support the current implementation of it. But I am against recreational drug usage and widespread drug availability (i.e. go to CVS and by meth and heroin, if you want).
I think that cigarettes and alcohol, already legal substances that ravage the poor, have caused and continue to cause immeasurable damage to life and property. Yet we do little to address those problems. Once drugs are legal, you'll find something else to blame poverty on ("the government isn't giving out enough free contraceptives and abortion services, that's the real root of the poverty cycle").
Study history, and we find that declaring war on those things increases the collateral damage and massively strengthens criminal syndicates.
