YANBU, the article is ridiculous and the adult-fed lines in it, supposedly uttered by a 10 year old, made me cringe.
Males are males, females are females, children are children, adults are adults. Nobody needs further sex/gender/body labelling.
I used to be very pro trans acceptance and have now gone very much the other way and becoming quite TERF. But the one thing I would say in support of the trans agenda is that I think there's too much dismissing of it in this thread by saying that it's all about what toys you like, what colours you like and what clothes you like. I think that's unfair. Many trans individuals feel a deep rooted horror of their born sex/body and believe that, regardless of what they do in life, they cannot ever be comfortable or feel right without changing 'gender'.
However, I think that makes gender dysphoria a mental illness akin to body dysmorphia, eating disorders etc, not proof that someone has been 'born into the wrong body'. It should be treated psychologically, not physically. And, if any hormonal differences are found in trans individuals then, as a pp said, why don't we correct that balance instead of enhancing it.
I think adults should be able to act and live as they wish, as long as they aren't hurting anyone. But it doesn't mean I believe men are women and vice versa and I definitely don't believe it should be posed as a valid option to impressionable children.
To me, encouraging a physically healthy 10 year old to consider whether they might be happier being the opposite sex is pretty much the same as encouraging a physically healthy 10 year old to consider whether they might be happier being a very different weight. We don't follow up a (healthy) child's concerned 'I feel fat' with support to lose unnecessary weight and become too thin. So why do we follow up a child's concerned 'I feel like a boy' with steps to become one?
