I suspect the truth is a lot more jarring/disruptive to your worldview than you might be ready to admit. I’m positive that you’ll shoot the messenger. You’re so close to the answer. It’s staring you right in the face.
The unfortunate truth is: The people (tribe) that you’re (rabidly) in support of are merely using those identity politics dogwhistles so that you’ll continue voraciously gobbling up the increasingly miniscule table scraps from the ruling class while thinking to yourself that you’re the last bastion of resistance against some great encroaching evil. When conservatives accuse the DNC of running the media, they’re not wrong. The DNC and their stable of “diverse” demagogues are masters of stage-managed, focus-grouped mass marketing. If they tell the truth, they are quickly disposed of.
