Make one donation, you will get one piece of junk mail, every week, for the rest of your life from them.
Then they sell your name to other like minded orgs. All of the sudden you wonder how PETA got your address.
Actually, the RNC and the NRA taught me a lesson about mailing lists...I gave to Nader with a money order and no return mailing address. And specifically asked them to keep me off all lists...
Between the RNC (And all the people who buy their lists) and the NRA, my mailbox was almost rendered useless...I finally called them both and told them to... "STOP BEGGING FOR MONEY OR BUY ME A POST OFFICE BOX!!! I'M ON THE TEAM ALREADY!!!"
