I think they're both good points. An unwillingness to call out bullshit itself leads to a systemic dysfunction but on the flip side a culture where everyone just rages at everything simply isn't productive. Pragmatically, it's important to optimize for the desired end result. I think that's generally going to be fixing the system first and foremost.

It's also important to recognize that there are a lot of situations where calling someone out isn't going to have any (useful) effect. In such cases any impulsive behavior that disrupts the environment becomes a net negative.
