This segregation stuff does not make sense to me, it almost feels like prison rules - keep genders/races away from each other because if they interact it will probably be violent.
I wondered what would happen if I created a community where the core culture was set by women, and the software and product decisions were also made by women
-> This also seems strange to me and counterproductive. If we build a society where any interaction happens without confrontations against the people that may be causing the issues, in this case "men", then how are we to make progress? Do men and women think differently about the merits of different software technologies or not?
Even when members have opposing views, they’ve given each other the benefit of the doubt and continue to talk productively.
-> Are you implying that men are incapable of this? Or that an environment where men and women interact is incapable of achieving this? Seems regressive...
This is tangential to your point, but I'm pretty sure what you're referring to isn't being "triggered." It's, I don't know, disagreeing? It has a specific and important definition, and it seems to be getting thrown around in other scenarios, to the detriment of those with PTSD.
