Perhaps you need to remind your folks that 65 years ago, good guys with guns stopped a madman and a mass murderer. Remember, one of the main reasons that Uncle Adolf was able to push his agenda through so quickly was because of his gun control policies at the time. If the Jews had had access to firearms, things might have turned out a lot differently all those years ago......
Just food for thought, brother.

You are singing to the choir... That message has been delivered but they are parents, they are older, they know everything & they are always right. Best thing is that they are also capitalist and vote right wing as best they can.
