They are very much like drug legalizers in this regard.
"Chesterton's fence is the principle that reforms should not be made until the reasoning behind the existing state of affairs is understood."
The 'reasoning' behind the existing pot criminalization is that unemployed Prohibitionists whipped up a frenzy about crazy Mexicans and white-woman-seducing Negro jazz listeners - a 'problem' every bit as bogus as globull warming, and manufactured for the same reason: more power.
Nope. That's just pro-pot propaganda. You may be surprised to discover that the forces of evil will lie to you about such things. Lying is what they do. You need to stop believing and repeating lies from people with an agenda.
One of their best techniques is making people THINK they understand something. We are witnessing these atheists right now who THINK they understand what they are doing too. They can match your pro-drug propaganda with anti-Christian propaganda of their own, and they will also tell you that it's true.
They will point out the Crusades and the Inquisition, and the various wars in Europe. They will point out the Salem Witch Trials. They will put forth all sorts of assertions as to why Christianity is evil and bad, and needs to be eliminated. Never doubt that it all links back to the father of lies.
