How so? If there is a set Age of Majority, a placemarker at which a person takes over advocacy of their own Rights having been deemed to be an age at which you should have enough life experience to do so, then you should be able to do all those things that other adults do without asking your parents/guardians permission. Otherwise, your parents/guardian is still responsible for making those types of decisions for you are are directly responsible for the consequences of your actions. As for what age my children will be getting my permission to engage in such activities? They'll be adults before they get my permission. Isn't that what a PARENT is supposed to do? When did such things become the GOVERNMENTS job? Do you approve of a Nanny State government? I am not sure what you mean. Do you support the implementation of a government controlled legal age of majority whereby certain citizens, based on an arbitrary age, are denied by the government from engaging in activites that are legal for a certain class of citizens only because they have reached that arbitrary age?
Do you support the implementation of a government controlled legal age of majority whereby certain citizens, based on an arbitrary age, are denied by the government from engaging in activites that are legal for a certain class of citizens only because they have reached that arbitrary age? Not at the Federal level. No. The Constitution has specific age requirements for certain things like voting, holding offices, and for labor. Those would require changing the Constitutiton to amend. As for the States, it should be up to the people of each State to enact such legislation.
As for the Age of Majority itself. It is a logical enough legal fiction. I have no problems with it being set at the State level. Better yet would be setting up a testable metric for it. People do mature at different rates, but you really do need to have quite a bit of experience under your belt before getting "kicked out of the next" so to speak. Some may never quite gain that ability. Regretable, but it happens.
