Online petitions have helped stop several companies from doing things their consumers didn't like. Public pressure via social networking seems to be the new "it" factor. I don't know the overall success
of this movement but I've seen several things on Change.Org
that had companies changing their ways.
The problem with the CFA issue is that we don't out number them. I don't even really think it's a close race. There are people in the gay community who enjoy their chicken more than they value protecting their own civil rights. I don't fault them but it just pads the stats when we have people who will continue to eat there no matter what their sexual orientation or religious belief is.
It's sad that food that is fast, convenient, and terrible for you can make people accept that their own civil liberties are being hindered by the company mass producing this food. For example one of my fiance's superiors is a lesbian. She said she didn't really care who CFA donated to that she liked their food enough to ignore it. I'm sure there are many more like her.
I don't think standing in front of the store kissing a girl will accomplish anything. It would be a cute default photo for Facebook for a day or two until the smoke clears and it's back to business as usual. I'd rather give my money to people who can orchestrate a larger campaign that will have more success than happy feelings for a day or two on Facebook. I'm just saying, we all value our contributions differently. If anyone wants to post pics of themselves making out with the same sex tomorrow I will gladly share it on Facebook to get a few likes and the random "WTG" from someone I never talk to IRL any ways.
