Oh dear, I have to do my research to get back and offer what I hope will be a valid rebuttal. I read your blog on hormones/gender determination. This is where I think I'll have to begin. Hormones are certainly powerful factors, but what determines those? Are there epigenetic influences that help to regulate those hormones? Can we ever truly separate hormone secretion from social influences? Two articles I found in a cursory Google search hint at the direction of my reading: Epigenetics meets endocrinology and Prenatal endocrine influences on sexual orientation and on sexually differentiated childhood behavior. I think, in order to have a purely objective discussion, I'll have to leave gender out of it. This is a charged subject. Better to look generally at how social/external/epigenetic factors can influence hormone secretion. Right now, I have nothing meaningful to say, but I hope that will change in the future.
Good, provocative blog--obviously got me working :)
