Gender

[Anomalocaris]

Elliott Page is an actor who was born a woman, possesses female equipment and DNA, and now claims to be a man. I was born as a man possessing male DNA and male equipment and also claim to be a man. What is the common thread between they and me that we share to identify as men?

You both feel more comfortable assuming the social role that, by a range of historical contingent circumstances some of which are quite disgracefully discreditable, the culture considered to be that of the men.   

I would think it is so obvious even you could not miss it.
