Rather than seeing each other as cousins, some of the most racist anti-black statements I've heard have come from Hispanics and Asians. If anything, adding immigrants will weaken blacks' position.
You can clearly see the Jarret stle contempt for the white man in her latest rant. 0’s being in office has clearly become a coup to kick the white men from the perch and change the country into “something else”.
I don’t doubt what you say about sentiments expressed by Hispanics and Asians towards blacks, but politically speaking they are cousins, very close cousins. They all favor the Democrats by wide margins.
It may be that as Hispanics’ numbers surge past blacks that the power of blacks within the Democrat/Left coalition will weaken, but in terms of policy it won’t matter all that much because a Hispanic-dominated Democratic party will support and implement the same policies favored by the blacks. The Democrats will still push to take money from whites and give it to all non-whites. The Democrats will still use racial preferences for all non-whites (except some Asians) in college admissions, public hiring, and public contracting.
So it may not be black Democrats at the forefront pushing these things, but the results will largely be the same.
That's because they haven't been subject to two generations of guilt-tripping and educational/media indoctrination, like whites have.
