I've never donated to SGK because they spend a ridiculous amount of money suing other charities and have outrageous overheads. I don't like charities that run themselves like corporations. So their recent decision is not really all that surprising to me and just further assures me of their goals and attitudes.
Also, while breast cancer research and awareness is very important, I've been donating/doing awareness for heart disease, which currently kills more women than breast cancer (indeed, all cancers combined.) Here's research from 2007 that supports this: http://www.cdc.gov/women/lcod/
(I have handouts with more updated charts that show pretty much the same thing.)
I have a lot of controversial feelings on breast cancer research funding, how much of it actually gets to where it is supposed to go, and if we're targeting the problem correctly to begin with.
Additionally, I hate the color pink.
