Why they target the young, is that the young have nothing in terms of worldly posessions, and are unsure about the future. Insecure in a big world and how to navigate that big world. The promise of a paternal government is easy to present to those who are only a few steps from the protection of their parents.
Yep, they now target kindergartners.
They can never be too young and they want the guvmint lefties to teach your kids because parents are not brainwashing them to be nice little robots.
