This is all wrong.

As long as the minor has US citizenship (through naturalization, parents, ect) they have citizenship. We can see this with ICE deporting non US citizen minors (there might be a rare exceptiom, but those are outliers).

Minors have constitutional rights as they have been ruled by the US supreme court to protest politically in schools (as long as it doesn't interfer with school operation or other students). They even have the ability for the second amendment as long as they are provided permission from the parent and is under adult supervision (hunting, target practice, compitition). Also still protected against unconstitutional searches or seizures.

Minors are not wards of the state unless they are sentenced to a correctional facility, some kind of state mental hospital, or orphinege. Children are under control of their parents unless some substantial reason (parent or guardian death, judification, extreme mental health).

As the other poster stated, children have protections such ad labor laws, protections against military service, protections against adult criminal trials (unless ruled by a judge).

(some of this will vary state by state, but most is the same)

Minors (except immigrants who have not been naturalized) are citzens, and they do have rights. For example, minors can be issued passports, and cannot lawfully be deported. That's because they're citizens.

Also, you can't just walk down the street and kill a minor. That's an example of a right that everyone has, regardless of whether they're citizens. Generally, the Constitution refers to such people as persons rather than citizens.

The vast majority of minors are not wards of the state, the only exception being those who are declared wards of the state through explicit legal procedures.

So nothing you said was correct.

The real rationale for Roblox being full of shit is that minors cannot execute contracts. And there are what are called unconscionable contracts, which are invalid even if the signatory is not a minor.

Not a single thing you said is correct.

Is that so? It would be a bit strange for me that children have no rights. What would prevent child labor or protect them from abusive parents otherwise?
