With regard to the Standard article about not constantly referring to pupils as girls and boys (as opposed to something gender neutral like students/pupils) is actually a really good idea, even leaving trans issues aside.
"The Gender Delusion" explains that references to gender of students makes their gender salient and makes them feel stereotype threat which can undermine their performance in subjects/tasks which are stereotypically done 'better' by the opposite gender.
WRT trans ideology, my compassion for people who want to live life differently, who reject the gender box they have been put into and be accepted as individuals is strong.
But I'm not really sure I understand the gender identity stuff.
I am a woman and feminist and I think that in general the tight boxes of gender roles and stereotypes is a bunch of bullshit. Clothes, hairstyles, hobbies, jobs etc shouldn't have to be a product of your sex. I'm clearly female, and there a few stereotypically feminine things I'm interested in but mainly my interests are neutral/stereotypically masculine. I have little time for clothes/shoes/hand bags and whatever else all women are 'supposed' to find fascinating.
I seriously wonder whether being trans would exist if sexism and tight gender roles didn't.
As I said I have every piece of compassion for people especially teens who feel they don't fit and are looking for an answer, a label to find their tribe. This feeling otherness is really common and I wonder if it is part of growing up and understanding yourself as an individual. But it might also be caused by having a different sexual orientation, having/being aspergers/HFA, or simply having different priorities from the people around one.
That said, I've listened to people try to explain the gender identity thing and I wonder if it is invisible to me because I don't have that feeling of discord, the way that if someone had never heard of being homosexual, they might not understand sexual orientation because they assume that sexual feelings for men is just part of being female.
The whole non-binary label sounds odd to me because it would probably apply to me but I've never felt that I was genuinely expected to be absolutely binary, growing up just before these labels beame well used and I wonder if it is a kick back against the odd increase in gender segergated toys/clothes. Its a label for just being yourself and it is a shame that some feel it is necessary in 2016.
Girls have always had less feminine female role models like George from Famous Five, Jo from Little Women. Maybe boys need the equivalent, like Billy Elliot, different ways to be Boys and Men rather than being put in a man box.
I feel that feminists are trying to tear down gender stereotypes whilst transactivists, also unhappy with their assigned stereotypes, are more focused on getting into the other box as a method of coping (which I have sympathy for) but I think the answer is not to put people in gender boxes in the first place.
Sorry for the ramble which is neither on message for being entirely supportive of the transmovement nor fully on message for the feminist based critique of it. It's my honest thoughts on it all which are a bit confused and may change in future.
