Looks forlornly at the pile of penis sheaths I have been whittling in my spare time.

"So long, fellas."

This is not just explainable with the concept of toxic masculinity but is a (admittedly trivial) example of how it negatively impacts men. They presuppose that the cause and effect is just one way ie: bad at video games -> toxic to female team mates, but they have not demonstrated this by studying the changes in the subjects attitudes and skills overtime.

Anyone who has played games or sports knows that you develop skill through dedicated practice and from learning from others. Both of which are dramatically easier to do if you are open minded and other players like you enough to play and share knowledge with you often.

I posit that there is a causative relationship of good sportsmanship (with all genders) leading to greater skill that is a potentially greater component of the observed effects than the masculine fragility alone.
