In fact, I've thought many times about forming a counter group, Drunks Against Mad Mothers (DAMM) but never really had the guts. After all, who wants to go up against a bunch of angry/sad mommies? It'd be like throwing a piece of fresh-baked apple pie at your mom or something.
But now, I think MADD is a texbook example of an organization that achieves it's objectives but needs something new to do with its fervor. So now they've been pursuing a kind of neo-prohibition under the guise of preventing drunk driving. I don't believe the original founders have much to do with it anymore, and have actually even renounced the organization.
They also push spot checks for drinking and driving which I believe is misuse of tax dollars.
I am against drunk driving, but MADD go way past the line.
