There is no big difference between assuming one knows, making shortcuts, or being judgmental. It might sound as if one or the other item on the list is a bad thing to do, whereas the other might happen by inadvertence.
I’d like to leave that assessment to others and the given context. Discussing other people’s intentions is generalizing something that depends on the situation and the people involved. It’s establishing a label that is attributed to the behavior of the person and thus pulling our attention away from the consequence of their behavior.
It’s teaching people by making them feel guilty instead of teaching people by letting them have an insight.

It’s wise to choose when winning is the most important thing and in which context it might be satisfying for everyone.
