I find this comment somewhat humorous because it pretty well sums up the frustration with "politically correct" movies to begin with; that the writer/director has an axe to grind and can’t stop themselves from souring their movie/TV show by turning it toward politics, especially when people are looking towards media specifically for escape from the culture war.
Or to put it more clearly: the way you feel about ycombinator comments here is very similar to how some people feel about e.g. LOTR or any other piece of media they otherwise treasure. I should think you might empathize with their position more if your politics weren't so opposed.
