What do they mean by "live as a girl", "be treated like a girl", " behave like a girl" "feel like a girl"?
Because what some of that stuff is likely to boil down to is:
- Hating the messiness and physical discomforts of periods and bras.
But who doesn't? And who doesn't feel it's unfair that boys don't have those problems?
It doesn't prove anything about anything, other than your levels of tolerance for physical things you find distasteful, and for life's unfairness ( and the luck of the draw; not everyone gets big boobs and period pains).
- Hating the discovery that in many ways, you will be a second class citizen in a nominally equal but actually quite sexist society. In particular, you will be seen by many as a sex object or as a failed sex object.
That's a problem with society, not with your identity. Some girls will recognise the problems more, and sooner, than others; and some will be more frightened or angry about it than others.
- The particular milieu you grow up in and what it considers to be "for girls" and " for boys" and "for everyone".
That is very much a moveable feast. A girl growing up in an environment which is inclined to "gender" behaviour and activities ( whether she is then restricted on that basis or not) will surely be more prone to this kind of thinking.
Yet the questionnaire seems to consider that the meaning and significance of those phrases is self-evident. It isn't. Framing the three things above as issues of gender identity is social and cultural and not even consistent across society.
