I'm serious.

People who are under a certain age have the most restricted set of rights of any group in the United States, with the possible exception of convicted felons.

They can't vote.
They can't sign contracts.
They can't serve on a jury.
They are restricted in the ways they can earn an income. Even if they do earn an income, it is rarely enough to be self-sufficient, and they have limited ability to control how the money is spent.
They can't consent to sexual relations.
They can't purchase certain legal substances.
They can't hold political office.
They can't drive cars.
They can't travel freely, instead needing permission from someone else.
They can't direct their own education.
They can be forced to attend religious services against their will.
They can't control their own medical treatment, and can be forced to take psychoactive medications against their will.
They can't choose where to live.
They can have their genitals modified without their consent.

Do I really need to continue?
