I guess it depends on what you consider fun. I can enjoy reading Heinlein or Clancy even when I don't agree with their biases, even when I see prejudices pervasive for the era.

But even the need for escapism is telling, since it implies what we're escaping from. It's much like the rap genres that talk about having extravagant amount of wealth and women, and the suffering to which that appeals is palpable.

Beating the tar out of the bad guy, or seeking some heinous bastard get shot in the face by Bruce Willis appeals to the same thing that true crime fiction does (police procedurals: Dragnet, Law and Order, anything by Dick Wolf) they reassure us that justice gets done. Even if by a brightly colored fantasy vigilante. Or in the latter case, that justice is meticulously fair and impartial, and still gets its man.
