Haha, I know you're kidding, but to those who actually believe that, since when? Since when has a group with different interests or differences been a strength? Would a family where everyone spoke different languages be a strength?
Such a dumb saying. Similarity is strength. The more different the weaker. And the nefarious people that pushed it on us knew that.
Of course they did. I see gaining a lot of experiences from different places as a strength. It keeps you from becoming a one trick pony. But trying to get people with completely different cultures, interests and intentions to band together toward a common goal is challenging, time-consuming and inefficient. It has yet to be proven to be an actual success anywhere it has been adopted.
