If this was intended as a response to me, I don't see the relevance to what I said.
As for the lead story, that's been going around for a long time, and don't really see the relevance to most US political discussions. Childhood lead exposure can cause developmental problems leading to adult behavioral changes. Believable to me.
Quite recently under Obama the EPA did make a decision to limit mercury polution which got opposed by the Republicans.
If you accept that lead should be regulated then why not mercury? The EPA did a pretty good calculation that estimated the costs and benefits of mercury regulation.
As Multiheaded added, "Personal is Political" stuff like gender relations, etc also may belong here.
