I've been an atheist for a very long time, well over 1/2 my life. Growing up as a family we usually supported The Salvation Army. We donated our goods to them. We would shop in their store. We dumped change in the buckets at Christmas. It wasn't until I was an adult that I realized that they are a religious organization. And, based on their position statements on their website they are a religious organization that doesn't support the things I do. If I were voting, I wouldn't vote for them.
There are a couple of places local that I could donate to. I'm not really that fond of either of their stores. I find them kind of icky. They do good work, though, so I'm just being shallow.
So do I donate to the charity my family has always supported but whose values aren't mine or do I break out and start giving to some place new? (Of course, who am I kidding... I'll end up donating to the place that is open on the weekend since I'm not taking a day off to donate crap.)
