I think that if you really can’t understand the relevance of comparing racial or national or social or any other contexts to the transgender debate, then you aren’t really well placed to start philosophical debates at all. It sounds like you need to do a lot more reading, thinking and maturing to get beyond personal anecdotes to social and ethical arguments.
You also mix up gender and sex constantly, and don’t seem to have a good academic or personal understanding of the terms, which does require some further reflection. Equally, it’s a basic point that if you try to generalise and ventriloquise what others think, they can perfectly well tell you you are wrong.
Can you not understand that the requests of people to be treated as the “gender they transition to” is not a neutral request, but offensive to many women and in conflict with sex-based rights and protections? If you don’t understand this, you also need to do a lot more reading around this issue.
Bear in mind, too, that it was you who not only started this whole thought experiment, but also introduced all the personal detail about being a trans man, not posters, who were engaging with your posts. Why now complain that you didn’t expect philosophical questions and are annoyed at posters interpreting the personal details you provided?
All of this stuff sounds just a bit immature and teenage; and fair enough if you are a young teenager, that is expected — we understand that — but if you want to engage in a complex debate with philosophical thought experiments with adults who often have decades of thinking about these things behind them, you need to be a little more equipped with reading, research and arguments.
It would help to go away and read a great deal, widely, in the history of feminism, sexuality, ideas of gender, psychiatry and psychology, and so on (and, most importantly, reading stuff you don’t agree with, or don’t think you’ll agree with, as well as stuff you do agree with - it’s the only way to learn). Start by really reading some proper second wave feminism - it’s very varied and complex and has a long history - and some history of homosexuality and identity politics.
NB - there is zero research evidence for transgender identity relating to “hormones in the womb”. This is something people have been desperate to find proof of for decades (most often for homosexuality), and there has never been any serious findings that lead to this. (The environment in utero is so complex that how could you possibly expect to find any serious correlation?) However, there has been a lot of work suggesting that identity issues can be a form of social and peer contagion.
