Do you think that black southerners would agree with the statement that "amicable relations" had existed between the races for the past ninety years and that the supreme court decision threatened to undermine them?

I don't think the Southerners would agree with this because their race has undergone so much discrimination all throughout the years.  What they have now is something they have struggled for from their forefathers, and that makes them proud.  Even if there is a threat from any government agency, I think they already proved that they know how to stand for themselves
