They are saying that they are too young and incompetent to responsibly purchase and use firearms.
We should respond by proposing Legislation (not actually passing it) that the National Age for DL's, Cigarettes, University Admissions, Signing Contracts, having Sex, Abortions, Voting, and any and ALL Welfare Benefits be set to 21-25.
Going to Reform School for sex under 21? Not getting a DL, Foodstamps, Abortions, Free Housing, etc until 21? The would be placed FIRMLY in their places!
And if being under 21 is too immature to handle basic machinery, then they are OBVIOUSLY too immature to conduct walkouts and express Political Speech.
Bravo to the Schools who are expelling for Students' disruptive Behaviour. If they're too young to handle basic Safety Requirements, they are too young to cause Disruptions and instigate Rights Violations.
