I am boycotting Susan G. Komen, and as a mammographer, it does come up. I also dislike the pink washing, but I adore my "Save the Haboobs" shirt (not for the message but because it uses the word haboob which caused an idiotfest in AZ last year over using an Arabic word that might offend returning soldiers to describe dust storms! Oh the horror!)
I will be boycotting Chik FIL A, mainly because I do not want to contribute my money to a corporation that will in turn give it to organizations that are hateful and oppressive. Many people I love are gay, and I would feel like a traitor with every bite. Not so tasty.
I don't shop at Walmart...I haven't thought of it as a boycott, but I don't like them as a business. I used to shop there and SAMs, but not anymore. If God forbid I need something in bulk, I'll go to Costco.
As for gasoline, Shell is the only company that gives equally to Republican and Democratic parties, so when possible, my husband and I fill up at those stations. I also use Circle K, I don't know what they do...I've convinced myself that bc they are owned by a Canadian company they can't make political contributions.

it makes me feel better.
