Conservative raving twits are conservative raving twits, always.
Marijuana "poisoning"? Really? There is no fatal dose, other than being hit by a bale of it falling out of an airplane.
A lot more toddlers are dangerously poisoned by things like chewing tobacco, cigarettes, alcohol, bleach, drain cleaner & poisonous ornamental plants than by marijuana, but that's not what "conservatives" want to hear, is it? Of course not. They want to hear about the evils of something their trusted sources identified as "evil" w/o any factual basis whatsoever. As always, they Believe!, with a capital B and an exclamation point.
Why do they Believe? Because they've been propagandized & indoctrinated since they could first understand the meaning of words.
Why is marijuana illegal? Because right wing propagandists haven't figured out how to continue indoctrination when people use the stuff. Their head isn't in the target zone that's been carefully triangulated for generations. The emotional hooks & handles are different, not as prone to self righteousness & denial, nor to greed & ego, all of which are the bedrock of so-called "conservative" thought, along with a fear of being wrong about anything, ever, even shit they don't comprehend at all.
Stoners recognize Rush as a big fat idiot, The Sarah! as a total bimbo, Dick Cheney as a total Dick, and all the right wing gas bags as just that.
Nobody likes to lose their audience, particularly right wingers with Calvinist social agendas, so they'll fight like hell to make sure that the only legal intoxicants are both stupefying & addictive. They understand stupid- they exploit it all the time. It's their meat & potatoes. Parroting their line of shit is what our conservative posters do all the time, even as they're dumb enough to believe that it was their idea in the first place.
