It often seems like people that support the second amendment care about none of the others, and I'm sure in part that is true for a number of reasons, but that doesn't discount that there are many more "second amendment supporters" who are concerned with the broader spectrum of civil liberties, but whose views aren't necessarily represented because there are groups like the ACLU that represent "all civil rights except that one" and the like.
Are you also in Maryland? Have you considered (or are you already) joining Maryland Shall Issue?
