Another @TribeSteemUp question from here... "Can You Unite the Whole World?"
Basically, I would say the answer is no, by most definitions of unite.
However, I don't think that we have to unite on more than a couple simple things (respect for sovereignty & the non-initiation of force), and everywhere else we want as much diversity as possible.
Maximum creativity, problem-solving, and general advancement for humanity involves having a lot of different mindsets, a lot of different approaches, a lot of different points of view.
I'll most likely add more text to this later, but I've got to post it before shutting down, or I lose the Dtube upload.
