Americans came together in 1775-1781--actually became Americans in their own eyes--because you had strong communities up & down the original States, with recognized community leaders, who could set up Committees of Correspondence, and work with like minded folk in the other States. "Diversity," undermines the notion of cohesive communities. It has people walking on eggs, as it were, not to offend those who do not share the characteristic values of the "community."
"Diversity" is one of the most destructive gambits of the hard Left in their quest to dismantle the American way of life. It leads not to true diversity, but to a population abjectly unable to resist what is being imposed upon them.
Here is my current summary for what has been happening--that to which "diversity" is an increasingly significant contributor: Losing America's Multi-Generational Purpose.

In a short reply, it’s not possible to flesh out exactly what I mean, but I do agree with your attention to the loss of our cohesion as fellow citizens with a common goal.
I will read your extended comments later, and respond. I’ve got to go somewhere in an hour or so, and don’t want to rush through your comments .
