Mansplaining is described as a condescending explanation of something from a man to a woman.

This concept is dumb because of all things, you decide to make gender relevant? Not the fact that the guy is a jerk for his condescending explanation, but you add gender to make it sound worse. If anyone is pulling the gender card, it's the one making the accusation of mansplaining.

"Mansplaining" isn't a gendered issue. It's just called being a know-it-all. The know-it-all just happens to be male.
