I don't see it as politically related at all. The five or six church members were concerned with skin color, not political affiliation.
I think it's good so many of us are shocked, and I think those subjected to racism are more likely to cry foul and stand up for themselves, due to how far we've come. So what was the norm, is thankfully now so out of the ordinary, it's news.
We humans have a tendency to group and stereotype, to varying degrees. That won't end but we can certainly diminish it by looking at ourselves.
Racism & serving Jesus don't fit together well. This small group was very wrong, and I'm glad so many are saying so. All have sinned. Hoping this bitter few can let go of their hardheartedness and learn & grow. If not, they need to face church discipline.
Moo
I hope they are allowed to act according to their own conscience, the same as everyone else. After all, that is a God-given right (as in free will), isn't it?
