I look at these things differently. I'm absolutely not referring to the OP but I find when people say they donate all year long so they don't donate for unsolicited requests, they may not donate to charity at all. We donate all year long, and also give to charities when people show up at my door for causes I support. We have also canvassed for a couple of those charities (cancer foundation and heart-disease research, I think it was).
My wife and I have lost three parents to dreaded cancer so we donate to cancer research. When the cancer lady, and similar people show up at my door, I give them 20 bucks. I donate to the United Way, to Christian missions work, to our church, often for cancer research and to local school projects because schools are under funded. At this time of year, we donate to the food bank, Santa's Anonymous and certain others.
We feel this stuff is very important. We may not have Champion's income or lifestyle
but we're fortunate to be blessed with more than we need and feel privileged to be able to share some with others who are less fortunate. These charities would be in a big pickle if not for generous givers.
