No, don't go to Charity Navigator, go to Givewell (http://www.givewell.com). The quality of their research is much better, and they focus on the question that really matters: what effect your donation will have on the margin.
Or, every one of us could do something different, instead of loading all our eggs in one Red-Cross basket? Sorry. I don't see a reason for this disagreement. Anyone that donates time and/or money to help other people, whether they are on the corner of the street they are standing on right now, or literally thousands of miles away, is a good person in my book.
