I agree with pretty much your entire post, however there is a reason I only ever refer to Tandora as Tandora.
I obviously can't be certain, but it is my opinion that Tandora is male and, if I were to venture an opinion on possible children, it would also be my opinion that Tandora doesn't have any daughters, and in my opinion likely doesn't have any children at all.
I'm not sure if my post will be removed or not, I'm not being offensive (being male is not innately offensive, neither is being described as male, or being erroneously mis-sexed as male in this instance), and I don't think my opinions break talk guidelines, but I'm sure we'll soon find out if it goes pop.
Anecdote time! I suppose I'm a GNC woman, I don't wear make up, haven't shaved in years, don't wear stereotypically female clothing and stick to baggy oversized clothes, and I only have long hair because I'm too lazy to cut it on the regular, although it's usually up in a tight bun to keep it out of my face and to stop it getting caught in things - safety hazard!
In my life I've been mistaken for a boy 3 times. It wasn't a big deal, it wasn't offended, and importantly it wasn't relevant in the same way that it would be in a medical setting (obviously ha ha!).
I was in my late teens-very early twenties at the time and I was wearing baggy clothing as usual, which does a good job at intentionally concealing my very stereotypically female body shape from men - and I'm sure most of the readers will understand why I would want to conceal my shape from men without having to ask why.
The first time it happened, two young boys whispered to each other after they had walked past me "Was that a boy or a girl?", "Dunno!" - I smiled and carried on my day, they didn't mean any harm, I wasn't offended, and it wasn't relevant.
The second time it happened, I was walking my dog (now sadly long gone) and a man probably in his 70's out doing his garden stopped me to chat about her - she was a lovely looking collie tbf!
At some point in the conversation he called me "young man". I did not correct him, it seemed a little pointless and I didn't want to embarrass him by pointing out his mistake. He didn't mean any harm, I wasn't offended, and it wasn't relevant.
The last time it happened, I was on a night out with some friends in the pub, wearing the usual baggy clothes, but this time I actually did have a very short haircut, of the sort stereotypically found in male hair fashion.
I had stepped outside for a smoke and a young lassie came up from behind me, tapped me on the shoulder and said "Hey sexy! Can I have one of your cigarettes?", I turned around and she looked utterly mortified, upon seeing my face she recognised immediately that I was female and she just looked like she wanted the ground to open up and swallow her. I laughed, told her not to worry about it and gave her one of my smokes 😂
If only those trans identified males who have a problem with women who correctly sex them could deal with these type of non-events in a similar manner, the world would be a much happier place all round.
