As OP2, my problem with OP3 is that none of that evidence really refutes OP1, which is why I said that the connection is hard to prove, or disprove. There could still be an environmental cause for some of the increase. But because gender is socially constructed, the effects of social change obviously can’t be discounted.

Honestly I think we should take OP1’s thesis seriously, but not as proven. And as usual cut down on pollutants for the wildlife it does affect.
