At the end of the day, people who dislike the Dixie Chicks for utilizing their freedom of speech quit supporting them. People who dislike Phil Robertson for utilizing his freedom of speech will stop supporting him.
The problem with the Dixie Chick example is that a LOT of their base audience, are the same type of hicktards that would LOVE Duck Dynasty. But, fortunately for the Dixie Chicks, their international market happen to agree with them and their sales went through the roof. Now, the hicktards may WANT to support Phil Robertson but if A&E takes them off the air, they have no international market to fall back on. All that's left is to keep making duck calls.
Bottom line is, they are all so filthy rich, none of this will keep them from missing any meals.
