Bingo on both counts. I am so tired of hateful stupidity. (As if General garden variety stupidity wasn’t enough.)
But to my personal experience, there is a certain type of male ego, and certainly a certain type of white male ego, that is terrified of female intelligence and certainly black female intelligence. Both of these women are very intelligent, both of the men are very threatened by it and have therefore resorted to insults and bullying to deal with them. They have no other mental or psychological resources at their disposal to deal in any other manner, certainly they can’t rely on their own intelligence.
