Sometimes I'm just too mean even for me.
For some reason, I got on the ACLU's mailing list. The first letter I got from them, I sent back with a request to remove me from their mailing list. Since that apparently was interpreted as a request for more letters, I now stuff the ACLU envelope with letters from the RNC, Pacific Legal Foundation, and whatever other letters from more freedom-minded organizations that I happen to have laying around.
I realize such measures are almost meaningless, considering the millions donated by $oro$, but it still feels good.
Don't send them anything with your name or address on it.
