Hellenismos, BTW
Without even getting into the expense and medical risk of transitioning not be accessible to all, they're rallied to in part because the concept of passing has ever been a harmful concept for trans and cis people, holding up inconsistent and narrow ideas about how men, women or nonbinary folk should look.
It's people looking to 'clock' trans people that are the problem, not people who think woman is a woman regardless of if she has facial hair or flat chest.
There's nothing narrow about it, it's simply hardwired inherent human perception of male vs female. And that undermines your assertion, this is generally understood and trans people regularly seek to appear as their gender whether they pursue surgery or not and can take offense if someone doesn't recognize the gender they identify as. Regardless of whether a person is cis or trans or socio-political opinions, humans recognize gender predominately via appearance. Someone who is clearly a biological male, regardless of attire or how they identify, is going to be perceived as male by everyone including other trans people which is why the trans community demands "preferred pronouns" be a thing.
