I donated to the ACLU once, and after a couple months, I was convinced that at least half of what I donated was spent on routine mailings and phone calls to my home. I support their work, and I understand that outreach is crucial, but I can't be the only one who was put off by that.
Ideally, I could donate and NEVER receive any communication from them. Same goes for the blood bank I donate to at my university. I'll give blood whenever there is a drive on campus (very often), but I don't need to be called every two weeks and read a script for 10 minutes.
Oh, hell, yeah. I stopped donating to the ACLU for similar reasons. I've since moved twice, once across several states, and I still get phone calls and mailings.
Donate to the ACLU.
