[Serious] Please convince me gender is binary

[Brian37]

Gender is a biological trait and you can identify with whatever gender you want, but at the end of the day, MOST people are either biologically male or female.
There are people who are biologically neither or have components of both, so that there is no clear cut answer to the binary. These are rare instances.

I refer you to Caster Semenya https://en.wikipedia.org/wiki/Caster_Semenya
She would fall into the category of intersex (not male nor female or having attributes of both)
And here is a link the to intersex page. https://en.wikipedia.org/wiki/Intersex

Biologically gender is not always binary.
Identifying as a man doesn't make you a man, in much the same way that identifying as a dolphin doesn't make you a dolphin.

But those who go to the trouble of presenting themselves as a different gender should be treated according to our social standards of how we treat that gender.
We don't treat men and women the same in society. There are different expectations.

Legally we should treat everyone the same, but most people realize that money can often make many legal problem go away or the lack of money can create more legal and police problems that anyone ever needs.

I am nearly 54 years old and I feel that my age and the generation I grew up in does have a factor in how I view gender.
I view it from a purely biological fashion.

While a penis and vagina are definable that does not give bigots the right to decide for others what their brains say or their bodies say.  I would agree though, even on any other subject regarding social change, older generations are slower to adapt. 

Even on issue of politics, economics and religion, humans do not like to have their social norms upset.
