Interesting, I believe exactly that but I've never heard anyone else express it before. The idea of social constructivism, the notion that everything is a mere social construct, has been so ingrained in (western) societies that people assume every problem is one to be solved through social engineering. It just puzzles me why anyone would be so adamant to put naturally conflicting groups together. What is the goal? What are the benefits that are worth the hassle and friction? Maybe it's nothing but a naive attempt to achieve some utopian fantasy, or perhaps there is a less innocent agenda behind it. I honestly don't know. If you wish to expound on the subject or have any literary recommendations, I'm all ears.
