Red Cross is a Ponzi Kite scheme where funds raised from one disaster dont go to that disaster, but may support future disasters. They lost me after Katrina.

Another well known but dubious charity is Susan G Komen.

I no longer support large national/global charity efforts of any kind and instead direct to local/regional. Its easier to see and verify impact and ensure funds arent being abused for jetsetting for more fundraising to support the lifestyle.
