Consider a group that is more pro-abortion than any other surveyed group. More pro-abortion than avowed atheists. Because of their hostility to Christianity.
Consider a group in which certain members have felt, throughout history, to kidnap Christian children, tie them to a crossed post and drain them of blood to use for magical purposes, in mockery of Christ and the Crucifixion.
If there is not a blood curse on that group, no group is cursed.
