Are you a man who works in tech, writing code for a living? Do you work with women who do the same? Then you absolutely are at high risk of always assuming their code isn’t good enough… that you know more than they do, even when it’s their area of experience, even when they have years more experience than you do. Unless you are working to explicitly remove the sexism assumptions our society has drilled into you, you are also being sexist. That’s how culture works.

Please stop. Be introspective.
