This doesn't look like a response to me, since I never said that the left doesn't use boycotts. They're a common political tool and have been for a very very long time.
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.
