Do you realize these studies don't really mean anything? They definitely do not invalidate other viewpoints. Most studies have been disproved by other studies and such somewhere along the line. Maybe the right studies haven't been done yet to prove these ones wrong. Maybe they have, but I don't rely on google to back up my thoughts so I don't know.
With respect..posting links and such as answer to everything is not really giving an opinion.
I mean, fair enough if you believe these studies to be 100% accurate, no chance of any margin of error and that, but equally, if a study came out tomorrow that said the opposite, would you change your view?
The gender identity study you provided earlier. Could be disproved IF we were willing to segregate a few random children to prove that gender identity is indeed a social construct instead of biological. But such a study is unlikely (I hope) to be carried out as it is fucking cruel.
I feel that with more and more people allowing their kids to be who they want to be (eg. letting boys wear dresses rather than telling them no, and so on), cases of gender dysmorphia will decline rapidly over the next 20 years or so. I hope so anyway as it will be better for everyone in the long run.
