I've not read the other replies. But:
Not being happy with periods, breasts growing, being the subject of the male.gaze and being sexualised by men - totally normal feelings. I can't imagine there are many women out there who relished any of these ideas.
We are still living in a society where men treat women as objects and that is not ok, and it is not enjoyable being a person who is subjected to that.
Opting out of being a person subjected to that is attractive because then you can tell yourself none of that applies to you.
We are also now in a society that tells young people if they deviate from a gender norm, then they may be gender queer or trans. This is not correct. Gender norms stifle life and individuality. The option isn't gender conforming or trans. The option is be the sex you were born and do the things you like and wear the clothes you like.
I worry that if I were young now, I would be influenced into thinking I was trans. I never played with dolls and hated pink and wearing skirts or dresses. I hated my body, couldn't accept that I was growing breasts.
This wasn't about being trans, but about the fact men seemed to think they had a right to my body or to talk or comment about my body. It made me feel uncomfortable and as though I didn't belong to myself. I wasn't abused physically, but because of how I looked, I generally got more attention than I wanted and in an overtly sexual way.
I wore baggy shirts and jumpers and baggy trousers, partly to hide myself. I got told I was a lesbian because of that - I'm not, I questioned myself a lot but I know my security. My lesbian friends were some of the most supportive people I knew when men shouted homophobic slurs at me.
In the end, I'm a straight woman who doesn't conform to gender norms. That's fine. What isn't fine is being told by others that my non conformity means I must be gay or that I must be gender queen or trans.
I suspect that your daughter is having a hard time with her body and needs support and help with knowing she is lovely and self acceptance and self confidence is key.
I suspect the support for trans people is in some cases being extrapolated to over support or affirmation of trans identity when someone is merely gender non confirming.
When people are trans, they need support. I have absolutely no fear or hatred for trans people. I don't want to eradicate trans people at all.
What I am saying is that by not conforming with gender norms or strict gender stereotypes it doesn't make you trans.
