Anyone familiar with my own view -- considered, alas, "radical" (not in a good way) by many adults, including many so-called progressive -- knows that I maintain that our millions of citizens under age 18 should have equal right to self-determination, and be given equal opportunity to achieve that.
How different might things be if our youngest were voters? They'd be a powerful constituency whose vote politicians would covet. As a result, my hunch is that we'd have much more funding for education.
There is nothing frivolous about a declaration. A declaration is a laser that slices through vagaries, egocentric pretenses, and societal conditioning -- all the way to the gold at the center of your heart.
