Yeah I think there's been a string push against the personhood of minors in recent decades. I don't love all the decisions minors would make with more autonomy, but I've seen the consequences of full parental control over the lives of teenagers in trans teens, and while some have had good results, for others it's the sort of thing that makes you just kinda stare at a wall for a bit. Over a decade ago, when I was freshly out a teenager stepped in front of a truck because of her parents' response to her being trans, they sent her to conversion camps, they punished her self expression, and they guaranteed she had no hope for the future, then when their daughter died they didn't even believe her words that they had killed her.
Children's rights are complicated. No reasonable person thinks a 5 year old should have the ability to tell their parents that they want to live alone and have the state defend that right or to take the child without cause. But I think it's equally ludicrous to say that a 16 year old should be blocked from getting a vaccine they want because their parents oppose it (when I was a teen this was a hot issue for the HPV vaccine). In fact I think any child old enough for abstract thought should have plenty of protections as a human including from their parents.
Hell even beyond rights to privacy from parents and the right to bodily autonomy, teenagers are often currently being aggressively hand held to the point they don't know how to function outside their parents' guidance at early adulthood. Adolescence is supposed to be a period of gaining rights, freedoms, and responsibilities, of learning how to be an adult but before the training wheels are off.
And yeah my experience as a trans millennial had me strongly relating to cis gay people my parents age. Lots of broken families and too many dead acquaintances, but with strong community and cultural bonds. The community meant I always had people and even in a new place I could find family pretty quick, I just had to be family to those who found me.
Also seconding the person saying that your mom is awful, like wtf, just because I've seen worse doesn't mean I'll ever get over the petty shittiness of some parents.
