I feel like most of this is just a combination of pretty privilege and and the belief that women aren’t exceptional like men are. Women (and men) who express themselves feminine will get those prejudices worse than women (and men) who express themselves neutral or masc. But since femininity is sometimes also related to attractiveness those women do can have pretty privilege as well.

Men grow up with the expectation that they are exceptional, and that they are above women in most aspects. Whenever a man is not good at something, and there is a risk of a woman being better, they get insecure and lash out. Other men being better is fine, because they can learn from them and it doesn’t risk their masculinity based on what they learned. Learning and growing is generally seen as a respective trait, and hierarchy instilled on us tells us that we should respect our tutors.

High skilled male players are more likely to be respectful towards women because in their eyes their masculinity is not being threatened because they’re already exceptional and don’t need to prove it. This can be different when a woman is really skilled as well but it’s doesn’t have to be.
