I listened to the story about Q this morning and I've read multiple stories about this issue and I will say once again that no child should be transitioning before puberty and no one should be receiving any kind of hormonal, medicinal or surgical intervention until after age 18. What they do need is to be seen by a pediatrician, endocrinologist, geneticist and psychiatrist. There may, in fact, be a hormonal deficiency that can be corrected, but it must be appropriate to the child's DNA-based gender.
Children are too young to know what exactly is meant by gender, and the hormonal changes at puberty might make a huge difference in a child's perspective.
What I think we should recognize is that gender roles may be more malleable or less defined, but that doesn't necessarily correlate with a gender transition. I am a woman, married to a man, and I have always hated pastel pink and loved playing sports and spent my childhood dissecting things (I had my own dissecting kit and microscope), but that was part of my geekhood, not gender dysphoria. I just found girl stuff a bit banal, but that didn't mean that I didn't recognize that I was a girl. There is a HUGE difference between enjoying various activities or colors or wearing certain clothes and gender transition. And, by the way, loads of women enjoy wearing jeans and t-shirts, not because they are or were formally considered men's clothes, but because they are more comfortable and they were being withheld from us because there was a preconceived notion about how we women should dress. Again, that has less to do with gender dysphoria or a desire to change gender than it does a desire to be comfortable.
