Agreed.
There's also an interesting localized effect where living around Hispanic people bolsters white identity:
So, while "diversity is our strength" might make a nice slogan (or the cornerstone of a new religion, whatever), it seems like in practice what you wind up with is increasing racial polarization. People in Iowa don't really know shit about white identity politics, but people that live in communities with lots of signs in Spanish start to notice that
maybe American whites and Latinos aren't
exactly the same in all important ways. They might start to notice that there's some measure of nationalistic solidarity between the folks flying the Mexican flags and that maybe it's not
actually a sin to express that kind of solidarity.
So, yeah, I remain skeptical of the "if we import enough Latinos, we can't lose!" belief espoused by Democrat analysts.
