We're doomed

Segregation of any kind is never the answer. Same with how the UK is looking at breaking apart, or leaving Europe altogether. Breaking people apart only makes them weaker. It's better to stay together and work on problems as a unified group than simply walk away from each other.

Give me a single example in history where mankind has benefitted from racism, sexism, or any other kind of bigotry. And I don't mean putting criminals in jail, I mean a country breaking in two over different ideas.
Call it too strong a word, but bigotry is what makes people build fences and walls around their homes. It's a deep-seated subconscious desires to protect their land from anyone else, it's the kind of thing we needed when we were cavemen, but don't need at all nowadays.
But we continue to do it, building walls, fences, and even entire buildings to keep certain people in certain places. Without even realising it we're enforcing to ourselves, and to our children, that people DESERVE to be separated.

My point was people want to build more walls, shut people out / in, and keep everyone seperate. Feminists call for women-only locations, BLM wants black-only locations, etc... without seeing how this is harming everybody
Borders are still a problem because they act as barriers and keep everybody locked in their own area, rather than being able to embrace each other. It's not about what we can share, it's about why we shouldn't share anything.
