I think diversity is undermining democracy. Democracy only works when people on opposing sides of the political aisle are still close enough that they will accept the opposing side being in power. People are more likely to do so when the differences between opposing sides are minimal. As the differences grow, eventually the divide becomes too large such that opposition candidates are so remote from one's own views that their being in power is not something one will support. Folks like Omar and Talib, their 3rd world Islamic value systems are so remote from my value system that I won't accept people like them calling the shots and I won't respect it. I don't want to share a democracy with such types and I don't want them having any say over how my government is run. They are too far from me.
Let's not forget America fought a civil war when the voting population was almost 100 percent white and mostly Protestant and nearly universally Christian. Even with such similarities between Americans we still fought a civil war. Divisions are only amplified the more diverse society is.
Also once it gets to the point where you feel candidates that reflect your views can never win, then you will look for alternative systems where you stand a chance of having your preferred candidates in power rather than a system where this isn't even possible.
What would a democracy look like in Israel I'd say for example Jews were 50 percent of the voting population and Muslims were 50 percent? It would be very dysfunctional because there is just too big of a divide between the two groups. The problem is that the elites say, we must have forced diversity and people need to learn to be more tolerant, and while they may feel that way they can't force others to be more tolerant if they don't want to because the opposition is just too different from them. Democracy works best when people are similar to each other with similar views. It doesn't work when you have widely divergent views that are incompatible and inconsistent with each other..
AOC's Hugo Chavez like views are not compatible with my views. She wants to change America's demographics so more and more people like her flood our country too and wants to change our demographics to the point that folks like me are a small minority with no hope to ever call the shots. Faced with this situation democracy becomes untenable. I won't support it anymore.
