I don't propose to ban alcohol. They have the right to drink. They also have the right to face the law if they are caught committing a crime while under the influence.Then why do you ban drunk drivers? They have the right to drink and also the right to drive a vehicle and until they cause harm are their rights not being infringed upon.
Just like I have the right to own an AR. I also must face the consequences if I commit crimes with my AR. That doesn't mean that people who don't commit crimes with their AR's can't have one. If someone robs a gas station with a double barrel shotgun and kills the clerk does that mean that we should then ban all double barrel shotguns? Who knows, you fudds could snap at any minute with one of those dangerous things?
