I totally agree with the extreme example of nazism or something like that, or most less extreme examples of prejudicial behavior, especially when that person is managing or just in any way talking to others. The problem is that it isn't so cut and dry. Too many of these people either aren't actually doing anything wrong (Some truck driver with his hand out the window) or have done something that is comparatively minimal to what they received (Justine Sacco, for instance). It's not that these people shouldn't be reprimanded, just that it shouldn't be the default for it to happen in this public, permanent, and very often dangerous way.
The narcissism is real, if you're not closing your eyes to it. It's especially obvious when these people doing it have done what they're complaining about themselves. It gets back to the main idea, that you don't have to harass people to get your point across. Even the most egregious reaction, trying to take someone's employment (and most often the ability to support themselves and their dependents) can be done in a way that isn't public and permanent.
