The Internet is international, especially so if you share a native language like the UK and the USA do. My native language isn’t English, but even I got into their politics, or rather culture wars. And girls take part in that shit too. Mostly focused on different topics, but still.
One of the most prominent figure in the anti-trans movement is J. K. Rowling, who is in fact a woman and from the UK, so that kinda disproves your points. Not to mention that she is an idol for a lot of younger people, I don’t think I need to mention why.
Oh and by the way, your insults are a little embarrassing, especially when your arguments are just blatantly false.
The same behaviour was shown towards Russian athletes with regards to the invasion of Ukraine. Judging by your logic that would be, idk, anti-orthodox? Russophobic? It’s symbolic and has nothing to do with the their opinion of the people they are competing against. It’s not antisemitism, plain and simple.
