I witnessed such a joke, from a brogrammer -- he thought it was funny, but noone else did, especially knowing how sensitive the female coleague was -- someone broke a pot of plants and he said "Why should we clean it, we have plenty of women around here" -- I just know the guy, the tone of his voice, and so forth, and I know he just tried to be funny, but at the end of the day, that was a sexist remark, we knew it, he knew it after he said it, he should have apologized, but he didn't.
But that was the only instance that struk me as sexist, and the guy always helped female coleagues, in no way did see any other "bad behavior" from him, it was just that guys generally have thicker skins when it comes to jokes and jabs, and he was usually very friendly, I've worked in male teams that were outright toxic, he was nothing like that.
Of course, high school kids haven't learned etiquette and don't care, but we want to hold higher standards in the workforce.
