I finally had time to read the whole thread AlphaTransWoman had created and found it very interesting. It reinforced the uncomfortable feeling I had decades ago when I first tried to see what transsexualism (which it was called then) meant for feminism that the two might not be compatible at all, depending on how the theory underlying transgenderism is built.
For me the goal of feminism has always been in making societies view women and girls as human beings, of equal value and importance with boys and men, and not to box them into tiny rigid boxes where their function is seen as only being sexual, psychological, and domestic support staff. And that can't be done unless we get rid of gender stereotypes and limit the impact of sex to those cases where it really does matter if we wish to give everyone equal opportunities.
This does NOT mean biological determinism at all and neither does it mean blank slateism, but trying to create a society where all people are first viewed as human beings with their own set of skills, talents, and personalities, and only then, in certain circumstances where it matters, as sexed human beings with specific needs based on their sex.
Underlying this is my belief that almost all cognitive and psychological characteristics of male and female human beings have overlapping distributions and that how we behave follows from a complicated mix of biological, environmental and cultural factors.
So seeing Alpha argue that women are one rigid set of characteristics, men another rigid set of characteristics was rather troubling. A person can be warm and have empathy and also be ambitious and competitive, and a person can be cold and selfish and also not interested in competing at all. And so on.
It's difficult for me to see what Alpha's feminism would mean in real terms, given that in Alpha's view women are supposed to be submissive and caring and kind and not at all rational or interested in inventing new things or competitions and so on. Perhaps a form of benevolent patriarchy?
Based on what I see online, some percentage of transwomen do seem to hold similar beliefs, often combined with a focus of the sexual aspects of womanhood, and this worries me when we are looking for compromise solutions.
