I try and let companies know how I feel about their politics and how if I don't agree with them I will just as soon buy other products. There is a top rated diary right now about the secret Koch meetings and who was there. Mother Jones
magazine has a quick rundown of the participants. Most of them are companies that I would not use such as big financial hedge funds, industrial companies that make products for other companies etc. There are a few though that you and I might patronize from time to time. These include Jockey Underwear, Omni Hotels and Golds Gym. So I now know I won't be using any of those products anymore. Actually there is no Golds Gym where I live and I would rather stay in a Motel 6 than an Omni Hotel anyways.
Butt (intentional) what about Jockey Underwear? I just sent a note to their Facebook page that says "I guess it's time to go commando rather than wear Koch loving underwear." The comment has probably been scrubbed by now, but Facebook bombs to Jockey, Omni and Gold Gym are in order.
