I’m a trans ally and know several people who are trans (and I suspect have interacted with several others without being aware).
as long as someone is a decent human being they can identify and present themselves any way they like. I’ve shared a bathroom with a trans woman on a regular basis and have never felt threatened or bothered in the slightest way. I really don’t understand what the fuss is all about.
i will say that for certain sports, mostly contact sports, trans people can either be at risk or pose a risk to other players, or have an unfair advantage. I don’t have the answer to that. However, the trans people I know are usually just so bloody happy to be living in a way that makes them happy (and in one case, no longer suicidal) I don’t think my concerns over sports gets to trump someone’s rights to live.
a lot of the anti trans and gender critical talk reminds me of the late 80s talk around gay people. I know some Miners won’t be old enough to remember those times. It was rough for someone to be openly gay or lesbian. I recall a gym teacher at my school being sacked because she had a female partner - it was felt that, because she was lesbian, she must automatically be a predator and was unsuitable to be around children. Obviously now we would be very angry if that happened in our schools.
i think that, in time, attitudes to trans people will hopefully undergo the same shift towards acceptance that attitudes did towards gay people. At least, I really really hope they will!!
