Which companies have they boycotted? The recent organized calls for boycotts include Chick-Fil-A, Mozilla, Walmart, McDonald's, etc. I haven't seen the right calling for a boycott of companies that supported gay marriage initiatives. Seems like the left is more into boycotts than the right.
I was asked for some examples of right wing boycotts and I came up with just one organization that has organized a bunch of them. I did not have to dig deep to find it and I dug no further than that at this very moment, but they are not rare or hard to find.
Boycotting Monsanto because of pesticide injuries, gmo, funding opposition to gmo labeling, franken crops, etc. isn't even a matter of opinion.
This is like boycotting Ellen DeGeneres' show because she's gay, vs boycotting Chris Brown albums because he beat Rhianna.
