None of us can know if we feel like a woman. You could have felt like a platypus since the day you were born and you would never know because you've never had the experience of feeling like anything else.
The only thing we can know is that we have certain experiences that arise directly from having a female body, which is something that only people with female bodies can experience.
When people talk about 'feeling like a woman' they're generally talking about several different things which they confuse and associate:
a) feeling like they have a female body
b) having the feelings and experiences that arise directly from having a female body
c) feeling 'girly' or having an affinity (or acceptance of) for the sex based stereotypes which are assigned to women.
The problem is when we use these thing interchangeably we reinforce the sexist notion that female bodies naturally give rise to 'girly' feeling and behaviors.
I'm trying to understand your post but your list seems to be a mish-mash of those plus just personal morality.
"my experience of prejudice or the positives of womans' networks (b - experiences arising directly from existing in a female body), my beliefs that women are just as valuable to men, my belief that the history of women is important (both of these are personal morals which men can also hold just as often) and my memories or schemas growing up has shaped my identify and ego (b - experiences arising directly from existing in a female body)".
In a certain sense I suppose do 'feel like a woman'. I have a female body, I have always had one, i experienced a female puberty, exist in society as a female, and my female body and its cycles do impact the way in which i exist in the world. I reject the idea that any of these are something that a non-female can ever experience.
