In their shoes I wouldn't name the person publicly. Maybe I misheard or misunderstood something. Maybe it made sense in some broader context that I missed. Maybe their dog or their mom just died.

Or it could be that they're just an asshole, but there will always be assholes. Much better to make everybody aware of asshole behavior patterns. Then they're ready to deal with the situation, which they're much more likely to encounter than the specific idiot.

Well, it's a funny thing, right? You want to be professional, and sometimes people do things they regret. Everyone makes mistakes.

On the other hand, how else do people know who these people are? There's no way for us to know if this is a mistake or a common occurrence.

Sure, that's true. However, the reader could probably judge this reasonably well, a one-time occurrence could be dismissed as a bad mood, but consistent behaviour like this would disincentivize dickish behaviour in people...
