I don't think anyone's crying themselves to sleep over the failure of Ghostbusters, the alt right types tried as hard as they could to provoke a reaction, somewhat got one, and then declared "victory" when the movie tanked, but people were only getting mad because some of the actors were being attacked unfairly, not because they had a vested interest in the movie succeeding and were pissed off that it didn't.
And there clearly is a difference between what the two sides are doing. Yeah, when a movie comes out that has some controversial elements, some people of liberal persuasion will get offended and tweet about it or some shit. But on the right, you always see like some douchebag "influencer" declaring out of the blue that something is evil PC SJW brainwashing, and then all of their followers will come in afterwards and harass anyone associated with the project. When was the last time that left wingers actually organized a campaign to systematically destroy a movie to make a political point?
