This experience makes me sick. There are very different places, where people are generally polite and professional and even fun. And where a sexist comment would not go unnoticed. Hope your next job will be like that.

I once attended a hackathon around some humanitarian cause. Participants in general were nice. However, I joined a team, which had two kind of strong male characters in them. None of them would be able to discuss and think freely. One guy has worked in various startups. Without him telling me more about this, I could just infer how blame-driven his developer jobs were by seeing him interacting with the others. Really scary. The other imagined himself as an activist. So active, that in the end, we did not produce anything at that hackathon and I believe without these two males it would have been much simpler to actually get a discussion going and to have fun.

In general, the more educated and diverse people are, the more they are able to think and think independently. The more people are responsible for themselves the more they are responsible for creating a work atmosphere, that is healthy for all participants - because hate and exclusion lessen motivation and there is one thing that need to go out to all businesses and managers and hierarchical elements: You cannot motivate people - you can only demotivate them. And this can happen much faster than one might believe.
