It can be hostile - to everyone
"Code Q&A site Stack Overflow has admitted its community can be hostile to women, people of color, and marginalized groups, and has promised to do better."

"Code Q&A site Stack Overflow has admitted its community can be hostile to people"
If men's ego's are bruised they dust themeselves off and get on with life. God forbid that someone should talk condescendingly on the internet. It's like the idea that women receive a disproportionate amount of abuse on social media etc when the studies have been done men get more abuse than women but they complain about it less. What is probably happening is that because the sex of each individual is not obvious women get less special treatment and consideration and interpret the lack of special treatment as discrimination when actually they are being treated the same.
