I know there are lots of jokes about identifying as an attack helicopter, or men identifying as women to game the system, but I'm more interested in how this affects actual trans people who are making an effort to be accepted as the gender they identify as.
The way I see it, if I meet someone who, as far as I can tell, is a woman, then don't see why I should have any trouble addressing her as such,
But who is stopping you from addressing a trans person the way you want to address them? As far as I can tell, nobody anywhere. It is rather the opposite: trans activists demand that other people address trans people with their 'preferred pronouns'. The penalty for refusing this demand depends on the legal and social capture that trans ideology has made in certain jurisdictions.
and I don't see what would cause anyone to be alarmed when she uses the women's toilets.
Are you a female? Why do you imply that 'alarm' might be the only justifiable reason to exclude males from female space?
Why isn't it enough for women and girls to say 'we want a female only space'?
I think that most people would agree that this is common sense, but some jurisdictions have laws banning trans women from identifying as women when it comes to something as mundane as taking a shit.
No one can stop you 'identifying' as a woman. But they might be able to stop you entering a single-sex space if you are not the sex that qualifies.
To defend trans identity, in that instance, would be to oppose such legislation.
I would think that the ACLU's natural position is to defend a person's rights to privacy (people shouldn't have to prove their biological sex when it isn't necessary) and freedom of expression (if a biologically female person wants to identify as a man then why not let her?). What do you think their position should be on the matter?
It seems to me there is no barrier to 'freedom of (gender) expression'. What laws (in the Western world, I mean) forbid men from dressing in clothes marketed to women? Or women from dressing in clothes marketed to men? What law forbids women to have buzzcuts or men to wear makeup? (The military has differing dress codes for men and women, and that should be lifted. If you allow one sex makeup or jewelry it ought be allowed for both. But that isn't a trans issue.)
It seems to me the only freedom of expression that is being curtailed is a person's freedom to dissent to radical gender ideology.
You ask about the 'right to privacy'. How do you think, for example, a single-sex space violates a right to privacy? A person's sex is not a secret; the government knows your sex already. Indeed, if the sex of your child was meant to be a secret, parents all over the world for millennia have been 'violating' this right, by freely disclosing the sex of their children to family, friends, strangers. Single-sex spaces are an honour system already: what keeps men out of women's toilets right now is the fact that
men don't belong in women's toilets.
What 'right to privacy' do girls and boys have if someone of the opposite sex can be in their intimate spaces? Do you think an 11 year old girl has the right to not see an adult male's penis when she is changing? If you don't think she has the right not to see it, why have separate intimate spaces delineated by sex at all? Note that there's no right to privacy from your own sex being discussed: people never had that right.
