I'm not sure if black liberals are all that different from white liberals.
I don't think black liberals ideology wise are as "liberal". A decent amount have somewhat religious views too.
Your religious views don’t automatically have a bearing on your politics…?
If religious beliefs are strong, they generally have an influence on how you see the world. However, that influence isn't inherently conservative. Many left wing movements of the past were heavily influenced and driven by religion(eg abolition of slavery)
