People are outraged that you have not taken your outrage to the highest possible peak. I find the whole episode hilarious (not the issue, the Neogaf reaction). The rage fueled forum warriors aren't the type that will add value to this debate nor spark meaningful change. If you really cared, organize a mass letter writing exercise for example. Write to your congressman, write to the newspapers, write to the church boards, write to the chicken people, let them know how you feel and perhaps the volume of, and weight of the words contained within said letters may reach someone there.
Calling for a boycott makes you the antagonist in this piece. By all means let yourself be heard, but sometimes you have to move on and direct your energy towards more fruitful avenues. Try to spend your energy on people neutral to the situation, persuade them to help turn the chicken people's opinions into a minority opinion. Do it through dialogue, not antagonistic, outraged actions. I expect better from people.
EDIT: Fixed my language a little, have a headache forgive me.
