German Politician greets Parliament in 60 genders

Have the Greens asked their beloved refugees what they think of their "campaign for Acceptance of Gender and Sexual diversity"?

I propose three genders, which I think will make matters simpler:

MAN, WOMAN, and SNOWFLAKE.

On forms and legal identification, 'snowflake' will be expressed as 'S' followed by either M or F in parentheses to denote what you actually are. People with genuine mental or genetic conditions (diagnosed by a professional) who are undergoing or soon to be undergoing sex changes are not subject to this restriction, but their birth sex must stay on official record.

Simple.

I certainly understand why people are sceptical about every gender on that list, I personally haven't heard of many of those and I don't see how there's a difference between trans males and a trans men (although I respect people's rights to identify as whatever they want as it doesn't affect me in any way).

But what's with all this 'There are only two genders' stuff, surely you recognise it's not at all that simple? While many of the genders in the list are perhaps not founded on solid scientific research, there is for example, intersex which is a rare, but genuine thing that exists in biology. And in regards to the argument that claims that gender and sex are the same, even the Oxford Dictionary shows a distinction between the two, sex refers to biological differences, gender refers to cultural and social ones, so why are people so resistant to the idea of expanding the concept of gender beyond just men and women, it's clearly not that black and white.
