There has been an ongoing discussion about the presence of estrogen in the water system from the volume of women taking prescription birth control pills. I don’t know if there is any merit to linking the two, but it would be an interesting study.
What will be really interesting will be if/when enough evidence is found to make this a plausible hypothesis, in which case the FDA, if it is honest, would be compelled to order the immediate withdrawal of all birth control pills from the market.
The pill is not the only form of birth control, so there is no legitimate reason not to take this step.
It's conceivable that there might be a sharp reduction in gender-confused people as well. Come to think of it, perhaps gender confused people have a cause of action against the makers of birth control pills. I'm surprised some trial lawyer hasn't already thought of this. If the Pope were Catholic, maybe the RCC could take this on.
