I feel the need to add to my feelings on this, because I don’t like admitting that I am somewhat transphobic. I strongly believe in bodily autonomy and I think 18 is too old to grant it. For tattoos, piercings, health decisions and anything else relating to oneself, I think autonomy should be granted as soon as it is claimed. In some cases of teenage pregnancy, the conception itself is a declaration of autonomy, unless the parents gave permission, which would be weird. I’m not sure a minimum age can be set. I think teenagers should be able to legally divorce (reverse adoption?) their own parents too. I recognize that this is also an extreme view that would frighten most parents. It frightens me too. But I kinda feel like picking out specific issues like trans rights or abortion is ignoring an overarching issue of parental/societal control. Not too long ago it was fairly common for husbands to view their wives as property. Many if not most parents seem to view their children as property. Maybe someday that too will change. It’s not as though 18 is some magical age of self actualization. Some people will be dependent on their parents well past that age if not forever, and some people are ready to face the world alone at 15, maybe younger for some.
