I wouldn’t dismiss environmental factors too quickly. There is a well documented decrease in sperm counts in men in the industrialized countries, and the reason is not because of lack of nutrition, infections in general, etc. Most pesticides, even the older ones before the new ones which directly block reproduction in insects, had estrogenic effects. Consider also that these chemicals are sprayed routinely into almost all indoor spaces and we can’t avoid all contact with pesticides if we tried.
The problem of the rise of the homosexual culture is due to many factors, mostly social, but, as noted above, even the government doesn’t know all the effects of the chemical soup we live in.
Personally, I have severly limited pesticide use in my home for 20 years, ever since I became aware of the hormonal effects of pesticides. Yes, I put up with a few bugs, but they haven’t killed me yet.
