I'm not sure what I make of the proposed changes to the laws; maybe my thoughts are slightly coloured by the fact that I get comments and stares anyway, without being trans. Anyway, people were asking about being non-binary, hence my post.
I think you would get much less stares in the women's toilets if this stupid gender nonsense was abolished and there were more women who just walk around like human beings who happen to be female and don't bother to perform femininity.
You sound like a pretty normal woman, tbh. I was uncomfortable with my breasts during puberty, and had they dared to grow so large that I would have needed a bra, I might have decided to have them reduced. Like to you, it makes total sense to me. (A bit less nowadays as I have researched the dangers, but still) And there's ony very few women who like having periods; that's not unusual either.
I have made an effort, as I found feminism early on, to be comfortable in my body, and am now okay with my breasts being as visible as they get in a t-shirt, but suspect this may not be the case if the circumstances were only a tad bit different.
You sound rather reasonable, so I would suggest that you consider rejecting gender instead of identifying as non-binary. (Which still is a gender)
Because the way some non-binary identified females behave is abhorrrent, and I have decided to withdraw any and all female solidarity from that group. Many other women probably do the same.
I'd hate for a reasonable woman to suffer because she's mistaken for an aggressive gender-role enforcer.
And as you acknowledge that, whether you like it or not, your body is female, I don't think you fit in particularly well with the genderist group, anyway, to be honest.
