Did you actually read the "hard data" or are you just parroting here, because parroting is what people following dogma do.
No, what people following dogma do is ignore facts that are contra-indicative of their beliefs, or find arbitrary reasons to dismiss it. Which is what you are doing. You're alleging an issue without evidence, and when provided the evidence you just dismiss it. That's dogmatism.
You're right, it's possible that under the current system trans people are benefiting in this zero sum game. Although I question whether the bad feelings they're generating are netting out well for them. But it's still a zero sum game
Facts show that making spaces trans inclusive lead to less suicides and do not coincide with an increase in abuse of women's spaces (but DO coincide with a decrease in abuse of trans people).
This news SHOULD make you happy. If you genuinely care about women being safe, then the fact that trans-inclusive laws don't endanger women should be a cause for celebration; even if you do have other reservations. But, strangely, you seem insistent that, regardless of evidence, there ought to be fear. Almost as if women actually being safe isn't really your concern.
