I'm not familiar with this, but we ban lead pipes, and paint... Why does assholiness always become the cause celebre with rightees? Perhaps the ban is to protect workers who manufacture the goods from having to be exposed to the shit all day every day, saving workers from future cancers and their children from birth defects. I mean, if lead is poisonous, and there are equally effective materials without health problems then we are trading lives for a god damned guild entrenchment, not even for the $. And if you lose tackle in a river, that shit is getting straight into the food supply.
When your analysis starts and ends with, "oh, here go liberals again, I'm against whatever the heck it is" you lose my respect.
