Is the term ‘mansplaining’ sexist?

Excerpt

The term is commonly credited to Rebecca Solnit for her 2008 essay, which became a 2014 book Men Explain Things to Me. While Solnit did not coin the term, the book crystallised the concept and the term was born and quickly spread across social media and pop culture.

The technical definition of mansplaining is when a man explains something to a woman that she already knows, often in a condescending tone.
