I look at this way: Cap fought in WW II. He's no doubt heard much worse. That line made him a caricature rather than a character to get a laugh.

Great point. In Age of Ultron, when someone curses and Cap America scolds, "Language," I just about walked out.

I'm playing the video game Fallout 4 right now, dealing with the moral issues around the "synths" in the game (basically the hosts of Westworld, some with more awareness than others), and seeing that story being played out in Westworld is generating a freaky kind of synchronicity. (or synthronicity)
