So what? So does alcohol, tobacco, and probably Big Macs, all of which are legal (for the moment anyway, until the nanny-staters prevail).
Teenagers aren't allowed to possess any drug, whether legal or illegal. And beyond that, they are also subject to their parents' legitimate authority.
We're talking about real Liberty for real grownups here, as well as the pursuit of happiness. An individual's concept of those things isn't bound by others' narrow-minded interpretations, whether those of an individual or a mob.
As long as nobody's rights are being infringed, truly free people can individually determine for themselves what "the pursuit of happiness" means to them, even if it means drinking excessively, smoking like a chimney, or cliff diving, for that matter.
It really is that simple! All else is authoritarianism and arbitrary law.
So why are you trying to muddle the discussion with "think of the children" emotionalism? It's clumsy propaganda.
As a staunch conservative and classical liberal, I could definitely support Cruz.
If Cruz keeps this up, he's going to be a legitimate contender in 2016.
I can't wait to seem him shred the propaganda of authoritarian socialists such as Hillary and her ilk, along with their "gotcha" media lapdogs as well.
This time around, the marxists may actually have come across somebody that can't be ignored, dismissed, or marginalized. And, hopefully, there will be no significant skeletons in Cruz's closet.
Cruz has my vote over all other declared candidates at the moment. The more I see, the more I like.
