Sorry Jon, you've based this whole piece on a false premise.

You say "Mansplaining is the act of arrogantly explaining something to someone who knows a hell of a lot more about a subject than you do. It’s an amateur explaining to a professional how to be a professional." That's not mansplaining, because it ignores the imbalance in power that accompanies mansplaining.

You say "Most of the time the mansplainer has no idea they're mansplaining" but many women will tell you that this is false. Part of the gambit when men mansplain, is the belittling of the woman in question. Part of our irritation is not just that the mansplainer knows less than we do on the issue, but that they take the mic and control the dialogue because they're men - they have the power in the room. Like interruptions, it's often used to 'put us back in our place'.

Mansplaining cannot be done by women - the imbalance of power isn't there. Just as whitesplaining can only be done by white people. For any kind of 'splaining to exist, there needs to be a clear societal dominance (rightly or wrongly).

Your experiences may indeed have been unpleasant and irritating, but they weren't experiences of Mansplaining.
