Companies have a culture, it might not be your culture, and it's mental to expect to be able to walk in and attack it in the first six months then everything be sweetness and joy. Joining a gaming company and complaining about female outfits is roughly equivalent to joining the NRA hierarchy and then in your first six months standing up at the AGM shouting about restricting assault rifles.
Asking people about their sex life is dangerous territory but depending on the context people have conversations about that at work. It's probably the worst thing in this article I think and worth a HR complaint.
Other than that it's almost all "I saw men acting the way men do in a very male environment and objectifying/trying to sleep with women." Well yeah, if I joined the NRA they'd be discussing hunting and stuff I don't care about or even find offensive but it's kind of expected.
You can argue that every single company should have an extremely corporate/restricted culture when any talk about the opposing sex is banned, the upside is that people would have less opportunity to be offended, the downside is that you've just substituted a system of state police where people play very Machiavellian games with HR and don't see each-other as humans because the way that they can interact is extremely restricted.
I'm sure if I joined a small enough female-dominated company I could feel really uncomfortable with the conversation topics, and the way that men were talked about. I could then pin my colours to the mast in some way (it's a company making vegan stuff and I stand up and extol meat eating), get quietly ostracised and instead of being horrified by aggression and blunt social nuances, be horrified by gossip and social politicking.
Maybe everything should be completely corporatified but I just find the idea deeply depressing.
