Yeah, you'd think that work, but most gun control advocates have guns for themselves. It's no one else should have guns that is what is being advocated.
I'm specifically thinking of examples of a politician gun control advocate caught with his own set several years ago, all the Jewish groups in New York that advocate gun control while holding arsenals for themselves as a community to get around the laws, or even Israel lobbyists pushing for gun control here while Israel has all its (Jewish) residents armed with automatics - which aren't illegal over there.
So no, a liberal is just as likely to own a gun. It's no one else should have one. Or in Israel, where it's just Palestine that should be disarmed.
And for the support of this Declaration, with a firm reliance on the protection of Divine Providence, we mutually pledge to each other our lives, our fortunes and our sacred honor.
