I do not believe Autistic men mansplain more often than NT men.
Taking credit for others' ideas at work is typical and unfortunately is admired as being a smart competitor.
Incel is the ultimate mansplain and arguably the most toxic as the word was invented by a woman and had nothing to do with hate.
To accuse a WP member of "Mansplaining" would not violate WP rules as it is criticizing an action. If one is to use the '70s term "Male Chauvinist Pig" to describe a member is a personal attack and is a violation of WP rules.
