Thanks for sharing, this book looks like it’s an interesting read. Even if you look at animals.. pure breeds do better (when not forced to inbreed). In the wild, hybrids are usually rare (like the “Liger”, and if they do exist, usually carry health problems with them that their ancestors didn’t have, such as almost all males being infertile and displaying feminized traits due to being born infertile).

In my humble opinion, I think a world filled with different cultures, ethnicities and values, is a much more beautiful and capable world than a world where everyone is crossbred (which Biden said was the goal years before he was “elected”; unfortunately I can’t find that video anymore, you can still find him claiming Zionism as his flag though in many clips before he was president - but he stated by 2040, America would “eliminate whiteness”, there will be no more “White people”, which is a “good thing” we should all be looking forward to). I’ve watched videos with Rabbis saying they’re literally creating their promised slave class of “Mulattos”, or what some Zionist Rabbis refer to as “golems”.

I feel a diverse world is the best world. Like from the excerpt in the OP, a diverse world is filled with diverse cultures, ways of thinking and ways of being - this leads to different ideals and approaches to both problems and solutions. People can combine processes to make them even better. People can combine, share, and build on the technology of other cultures. And, you’d be able to visit and enjoy each culture as you please.

Who wants to walk into an ice cream shop where the only available flavor is a “black-and-white” (vanilla mixed with chocolate)? I know I wouldn’t, I’d want choices, and I’d want to experience the different flavors. I view Earth this way too - I appreciate many positive aspects, perspectives and universal contributions of cultures and ethnicities that are different from mine, from Japan, to certain South American cultures. A lot of the things I enjoy, I wouldn’t have if humanity didn’t put in a group effort.
