Good articles.
Yes - this is an existential question.
It affects everyone.
Do you care about:
Being able to use language that describes reality?
Having the freedom to believe in what you believe to be true (like reproductive biology) rather than ideological dogma?
People's (including women's) rights to self-determination, including services designed to allow for participation in public life and fairness in events like sports?
The GRA debate is not about a piece of paper. It's the fact that the authorities can force you to pretend you believe that men can be LEGALLY and LITERALLY the same as women - any man can say he is a woman, all he needs to do to legally be one is fill in a form. And a group of very authoritarian people can (and from what we've seen, WILL) pursue you using every mechanism available to them if you disagree.
We know that trans ideology isn't true.
To say a man is a woman goes against what you can see with your own eyes, what you know in your heart and in your head to be true. It's blindingly obvious. It does not take any sort of special knowledge to know that women and men are different, and that you can't magically turn from one to the other, especially not just by uttering a few words!
If a government will be able to compel you to go along with such a blatant untruth, what in the hell else can they make you do?
