The South isn't racist at all.
Interracial marriage probably didn't do well among people of any race in MS. As I recall, the Alabama referendum repealing the defunct anti-miscegenation statute back in 2002 barely passed in the Black Belt counties (except Montgomery) while barely passing statewide.
In the 2000 referendum legalizing interracial marriage, the Black Belt of Alabama voted heavily in favour.
That, and there is a very, very good master's thesis one can find on-line somewhere that does detailed statistical analysis of that vote. The conclusion: Said referendum was overwhelmingly supported by blacks, and split the white vote 50/50.
