The courage to say "shut the fuck up" or "stop being a piece of shit" to an asshole who is your boss or relative, beats whatever imagined courage is required in some batman fantasy violence scenario
And, it's courage that you can tell cishet white guys *entirely lack*.
It's very extremely obvious they're not telling their dipshit buddies and bosses to knock it the fuck off, every chance they get. Because there'd be a lot less dipshits floating around if they did.
