Men: build up for centuries being dangerous and tendency to domination of others as a virtue 'non-dangerous non-overly-confident men are not real men!!!'
Also men: 'how dare you call me "dangerous"!? I am very offended, boo-hoo!'

Also, not on this site, but I have seen women's complaints of sexism be disregarded in supposedly-leftist spaces, such as in threads authored by them and dedicated to them saying that they are excluded from various hobbies/spaces where some people commented 'nobody is complaining about being excluded!'
