They may have a 'goal' of banning ammunition sales by law, but I doubt that will happen.There are places where it is a very real possibility.
Nevertheless, they have the right to boycott and try to recruit others to that action. When such things occur, those who oppose the goals of those boycotting are free to organize an 'anti-boycott'.Or mock and criticize the motivations of the proposed boycotters.

True. And one would hope that the one mocking/criticizing the boycotters is prepared to be mocked and criticized himself. :)
