Mississippi and Illinois are two different beasts.Do you think that some change can also occur in states like Illinois and Mississippi, or do we have to surrender to the evidence that a part of America will remain excluded from the process of change that sees as protagonist those USA in which we recognize ourselves
I ask you this question because, living in Italy, I only know indirectly your reality.
For Mississippi, the state in the deep South, is deeply Republican, and is where some feelings among the older populace will hold on to feelings of Racism and Segregation until this oldest current generation dies out. But are there IR relationships? Yep. I think as time moves on, it will get more receptive to black men and white women having families, by marriage or by cuckolding.
As for Illinois? WAY different situation. Illinois has been Democratic for most of recent history. The last time it was a "Swing-State" was in the 2000 Presidential election, when Al Gore achieved 54% of the votes. It has moved firmly Liberal since. IR relationships is more common there, not through any form of social progressiveness, but out of a more common approach. Finding the right man to mate with. Now, that being said, we also do need to keep in mind that for the last few years, with the Biden Open Borders Policy, a lot of Hispanic and Arab immigrants have been landing in Chicago and environs. So it will be a complication, and I think that all of these races will be competing for available white women. I think more white males have become interested in experiencing their weakness, and so I think the Black and Muslim races will see greater progress in IR breeding.
