Yeah a big part of mansplaining is that you are explaining something you they already know (and assumed they didn't know because they aren't a man).

It is also generally when they explicitly tell them - "I know this, I am an expert" and shows you their credentials, and they still dismiss that and continue talking over them.

Like, a person can make an honest mistake. But if he continues to be condescending even after being told that the woman is an expert, that is definitely mansplaining.
