Research Proves 'Gender-Bending' Chemicals Affect Reproduction

And these are only what's known.

There are chemicals and hormones in the great lakes that people drink. Hormones can change people even after they are born. People use them for "sex/gender alterations".

Men are being feminized in society. It's a demonstrable observation. This can be partly due to social epigenetic factors from psychology to affect our behavior and change what we become, but I suspect actual physical factors like chemical and hormones are turning more men effeminate.
