My tone was probably a bit harsh because I was getting frustrated

You poor thing. A marginalised, discriminated group at risk of losing even more of their rights keeps arguing with you, instead of just accepting inequality. That must be frustrating for you

I am a trans woman myself so I understand how they feel. We're an inherently small part of the population and there's an extreme sense of vulnerability that comes with that. I think you'd understand if you were part of the demographic. I'm sorry that you feel frustrated though, truly, because I know that you mean well.

Once again I understand what you're saying and acknowledge that you're not coming at this from a place of malice (at least that's how I see it). That being said, I've never met anyone who actually had some of kind phobia of people assigned male at birth (AMAB), or trans women specifically, in the context that you're describing. I think it's a wedge issue that causes people to feel strongly without there really being much rational basis for it, which I think you acknowledged to an extent? We can't base laws off feelings or extremely rare cases where the person's true intentions can be challenged. In my experience, the only people who express any kind of fear of AMAB people are activists involved in groups that claim to focus on women's issues who have an incentive to advocate for transphobia. Sometimes they have financial connections to American evangelical groups, that sorta thing. Rape survivors don't tend to have that opinion in my experience, although maybe you've met some who thought differently, idk. Either way, I have to say from a personal experience that I don't want my rights taken away based off such weak arguments, and in the case of the US and UK, they rarely stop at segregated spaces, they usually try to remove us completely from public life in an attempt to force us to detransition.
