An invalid argument is a phrase that cannot be interpreted as an argument or not on the topic of gun control.
PROBLEM: (We all know those missile launchers, machine guns, and grenades are soooooooo easy to buy from your local gun shop, huh!)

SOLUTION: Valid

PROBLEM: Long the dominant view of the Second Amendment, and widely accepted by the federal courts, the collective rights model has recently come under strong criticism from individual rights advocates.

SOLUTION: Valid

SOLUTION:
Valid
