Relax man, I actually agree with you on the trans issue. What I disagree with is more the "radical feminist" part. Perhaps I should have used a different term? Anyway...
I'm just not sure how you can acknowledge the existence of sexual dimorphism and then immediately turn around and label masculinity and femininity as entirely "patriarchal social constructs", as if there are zero cognitive or behavioral biological differences between men and women. Do you not think it would be profoundly strange if the sex that rears children did not have a behavioral disposition towards caretaking, and a generally less aggressive temperament than men? Do you really think it's "patriarchy" that causes women to choose people-oriented and caretaking jobs such as, say, teaching or nursing over STEM? Maybe I'm just misunderstanding, but I feel as though people are too quick to dismiss the personal choices men and women make as something sinister rather than free will.
Feminists also tend to have these diametrically opposing views where a patriarchal conspiracy to oppress women still exists (again, with no supporting empirical data), that women are all helpless victims that need a crutch to survive in the "man's world"- yet simultaneously, women are strong, independent, and equal to men- and like Susan B. Anthony, perfectly capable of accepting equal responsibility for everything. I'm not convinced that a patriarchal country that views women as disposable would make most of their scholarships exclusively female-only, or give female business owners money for just being women, or lower STEM and military standards for women, or take a woman's word as gospel in a court of law, or make acts of violence against woman a much greater crime than the equivalent against men, or have laws that force everyone from small business owners to the highest branches of government to hire unqualified women over their more qualified peers and etc etc, you get the point. You won't see middle eastern countries doing this anytime soon. Hell, today we demand that people "respect women", but tell men respect is earned, not given.
You're never going to eradicate every sexist or racist or whatever from the world, but it's foolish to deny that women in the west receive preferential treatment in a great many scenarios. And that part doesn't even bother me. It's exactly because I admire independent women that I loathe feminism for teaching women that they are still helpless victims under the thumb of a faceless mob of men that hates them for having vaginas. Just my two cents.
Ultimately none of this matters when we're looking for porn. I like femdom and strong, assertive women as much as you do, and I can see you made a lot of effort in creating the list, so even if we disagree I have to respect that much.
