Being in my sixties I'm sure my mom was not subject to any food additives that affected me in the womb. My grandma cooked from scratch. It is possible for chemicals that are not natural to alter functioning. I know that from exposure to toxins that have altered some of my organs. I know it is possible for chromosome damage to be passed on through sperm which will cause birth defects. Girls are developing earlier than in the past. Kids are fatter and headed for diabetes.
I'll throw this out. If a chemicals and/or with nurturing may produce cross dressing tendencies, does that affect/encourage the development of gays and lesbians?
I think the individual and society should just accept what are person is rather than trying to figure out how he or she got there. Too much time is spent trying to understand and "correct" some traits that does not conform to the established/expected norms.
