Racism and sexual prudery.
Hatred of the black man (and the brown and yellow man), and fear and obsession with sex (abortion, contraception, misogyny and homophobia) are where the circles in the Venn diagram intersect. The economic elites have identified the spark that allows then to start the fire. The emotional fuel of fundamentalist Christianity keeps it lit and feeds it.
I don't expect much will come of this case. Its Georgia.
