I've spent much of the past couple of days reading about the behaviour of 'MTF' trans people. I was wondering how many people wonder if there is a biological root to some their behaviour (i.e. fetishistic, aggressive event to the point of violence, competitive with women). Apparently many/most have little to no medical intervention. I don't believe in pink or blue brains, but surely hormones influence behaviour somewhat - some of the behaviour of the more 'AGP' camp seems almost hyper-masculine to me?
