Very semantic of you. I think in the context of the argument the difference is rather marginal. But anyway, I take it that you disapprove the first instance of dismissing and marginalizing a whole population of very diverse people but approve of the second intance of dismissing and marginalizing a whole community of very diverse people?
It may be that I am simply misunderstanding the reference, but I don't think there have been any instances of dismissing or marginalizing any group, population, or community.
As to the issue of theoretical or hypothetical situations - well, I think this whole debate in this thread is concentrated on very rare and extreme cases which often then are extrapolated to rather theoretical extremes.
I don't think that's the case at all. I think the bulk of the debate centers on ordinary women in situations where a male is sharing their private space, or competing against them in athletic events.
Nova Maday and Terry Miller are not extreme or hypothetical. Neither is Caster Semenya, who started this thread.
The Loudoun County rapist is pretty extreme, although not in the least hypothetical. We're not yet sure on Darren Merager. Maybe Darren is a woman, in which case what he (as some people refer to him) was just behaving in a completely ordinary manner. If not, he is exactly an instance of a predicted consequence of trans-inclusive policies. It is possible that Darren's case might be unusual, but it is not extreme or hypothetical.
All of the cases that I read in the recently quoted Twitter post were extreme, but none were hypothetical. However, it seems unfair to dismiss the msot extreme cases as if they were insignificant. They are exactly what we expect to happen as a result of trans-inclusive policies. Those extreme situations are rare, but predictable.
And, going back to Nova Maday, who is neither extreme nor hypothetical, people dismiss the concerns about her. (To save googling, Nova Maday is a trans-girl who was granted unlimited access to the girls' locker room at Palatine High School in Illinois.) The girls who didn't want to take off their clothes in front of her (sic) were called bigoted and transphobic.
I think your reference to extremeness is, in fact, a way of dismissing and marginalizing the population of women and girls who don't want penises in their locker room.
I don't think this discussion much concerns the great majority of people who identify themselves as trans. Their lives, experiences and actions are not the stuff described and discussed here. And maybe they should be, who knows.
I think the people like Lila Perry and Nova Maday and any other penis -possessor who wants to use a girls' locker room is very much about the great majority of people who identify themselves as trans. I think the discussion of Terry Miller and any other penis possessor who wants to compete in women's or girls' sports is exactly about the ordinary people who identify themselves as trans.
The trans rights supporters, in this thread and in the mainstream, who dismiss the concerns about privacy rights or competitiveness in sports, are pretty mainstream for the trans rights community, and they routinely dismiss without comment any of the concerns about these sorts of "routine" transgirls. They don't merit mention, except possibly to insult the people who express concern. If it seems that the extreme sorts like Jonathan Yaniv seem to get a lot of the press because their behavior is so absurd that even the most strident trans rights activists can't completely ignore someone so extreme.
