I personally also feel sure it’s correct but I can’t prove that. That’s just a feeling in a woman’s head.
That's perfectly reasonable (and I see what you're getting at, I think
).
The thing is that the world each of us living are living in, despite being the exact same place, is probably a completely different place to each of us inside our heads.
My vision of a tolerant, inclusive and humane society is one where everyone's vision is accommodated as far as is possible without undue hardship caused to others. That doesn't mean no hardship, that just means a fair and equitable distribution of that burden between every single one of us, in order to achieve that society.
So to me, it's not fair and equitable that no transperson should ever be offended or assaulted or inconvenienced if that means women suffer extensively as a result. Likewise it's not fair for no woman ever to feel uncomfortable, inconvenienced or even (god forbid) be assaulted if the price of that is a far greater suffering to transpeople.
It's more complicated than that of course, but that's my general premise. So I guess my "it could be nature or it could be nurture but most likely it's both" is ideological too, given that the above is the position I'm coming from.
Hope you didn't mind me waxing lyrical a bit there, I went off topic!
