Of course I'm generalizing. A lot of people out there genuinely do care about real issues, and a lot of the "angry" Internet comments about how racist or not-racist The Jungle Book is are just in good fun, but it's weird that I can so easily compare the two types of rage. I have no idea how to objectively measure this (are any of you scientists? Can you science this for me?), but if one is more common than the other, it's not by much.
Why? Because one of those things seems like it's about us. If someone tells me that they don't like my favorite movie, then it's easy to ignore it, but if they tell me that my favorite movie is stupid, I can't help but feel like they're saying I'm stupid for liking it. It's a natural response, because I'm kind of a narcissist. But then it gets even worse if they think my favorite movie is racist, because being racist is even worse than being stupid. Ever hear the term "SJW"? It means "social justice warrior," and it refers specifically to people who point out racism or sexism in movies, video games, and other pop culture. Those people are considered worse than other types of critics because instead of just pointing out that a movie has flaws, they're accusing people who like it of being awful.
Except they're not, of course. If someone points out that the alternator belt in your car is slipping, they're not accusing you of being some kind of mustache-twirling, white cat-stroking supervillain for having car problems. They're not accusing you of anything. They're talking about your fucking car.
Then who is the bad guy? Well ...
