I like very much that the whole "mansplaining" concept and term was introduced to the world. I don't think I'm really a mansplainer - I don't actually think the ladies always need my sage knowledge - but I do get that sometimes I engage in discussion in a style which can probably be seen that way. I used to teach, so sometimes I go into "teacher mode," and like many people I can be a blowhard knowitall at times which isn't actually the same thing as mansplaining, but it can seem very much the same.
Still that there's a word and a concept makes me aware of the possibility, and I'm just a bit less likely to do it. Sometimes I do shut my piehole and let the ladies talk. Amazingly, they can have smart things to say! Hard to believe, but true.
