Not a transbian but i know exactly the lines you're talking about, they made me cringe too
I hate how gender is associated with sex
I've erased and rewritten this post a fair few times now before actually posting it, but in the end all I can muster is a feeling of absolute exasperation at comments like this (and others) and the piss poor and hostile responses to @Green777's reasonable takes, although I'll admit they seemed to go off on a tangent towards the end there. The dissonance between some comments here and how things actually go IRL is staggering, to say the least.
Some of you will get the shock of your lives if you try dating/forming relationships with other actual humans, relationships and dating are exclusionary by their very nature, there are certain things that will be a deal-breaker for a fair number of people regardless of how much you attempt to guilt or belittle someone into thinking otherwise, and that ain't gonna change any time soon.
