My opinion is that most gun rights advocates are hypocrites and/or lack the courage of their convictions. They will argue that even moderate government restrictions on gun ownership are unconstitutional ... BUT they claim to support the law that prohibits the sale of guns to convicted felons ... BUT they oppose background checks that are necessary to enforce the prohibition on gun sales to felons.
And my challenge is this: if you argue that restrictions on gun sales are unconstitutional, have the courage of your convictions and oppose the restrictions on gun sales to felons. If, on the other hand, you concede that the government should try to limit gun sales to felons, have the courage of your convictions and support the elimination of the gun show (or if you prefer, private sale) loophole that guts the effectiveness of the background check system.
