Now, I know the purpose of all this. It's supposed to elicit guilt. You're supposed to be so moved by them sending you all this guilt...I mean unsolicited garbage...that you will send them money. It's accompanied by various pathetic pleas and stories of "this demonstrates how little it takes to do x." Naked manipulation, I call it. Sorry, guys, but I'm using (or trashing) your cards and labels, but not sending you money. I put your spare change in my wallet. Call me cynical. I'm also getting more than a little annoyed with all of them, which isn't good for the causes they are obstensibly soliciting for. I'm hoping the non-response will eventually inspire them to stop trying to solicit me, but it doesn't seem to have worked, so far. And I haven't heard of an anti-charity list.
You know who gets my money? Good causes that don't send stuff. I have actually been moved to send money to relief agencies that state right out "Unlike some, we will not send you gifts, but we are hoping our cause will inspire you to donate..."
