Plus ones like xo. Or in fish, they don't even have the same types of chromosomes. And they can change and reproduce afterwards. So like. Absolute statements or applying false premises as though it's 100% true is outright wrong.
Yes, everyone has heard of those. You've most likely already heard the rebuttals against those too, so I have no idea why they are even being brought up. Mutations exist. Mutations are aberrations along finishing development process. Some people have six toes. Some people have supernumary teeth. But these are not categories. They are mutations.
And again, this all goes back to the null hypothesis. If you aren't willing to accept the possibility you could be wrong about gender being a feeling, why should everyone else consider themselves wrong? End stop, there's no set of data (xy and xx is the furthest regression we have right now similar to a quark being the furthest regression of an atom) that will get some people to believe men are women. The idea of 'well I hope you get fired bigot' is digging yourself into a deeper hole, that's not the right answer. When I say the best you can hope for is to agree to disagree with a large portion of society, it means 'I hope you get fired bigot' over time will not only alienate you from the reasonable population, but other transpeople who are trying to fit in and be polite with others who don't agree only to see you poisoning the well for them too.
Except trans people can tell you it isn't a feeling. If people ignore trans people when discussing the validity, they're being wrong.
You can't say chromosomes are an absolute then ignore all exceptions.
And you say that we alienate ourselves. When really, we're being pushed out of society by bigots like you who refuse to change, and who continue to make our lives hell until we die. Your feelings don't have priority over trans lives. So yes, I want you fired and removed from society until such a time as you can learn to not be a bigot
I'll supply you with one more burnt bridge on your long list. I'm probably the most reasonable person you'll meet acting this way, so with my plank removed you can go ahead and continue on your merry way to complete isolation compounded in these unreasonable interactions with others. Consider yourself not even a blip on my radar anymore, ignored and moving on with my life. I mean screw it I tried. I have no idea how many planks you have left, but oh well, here's one less. ---
