Progressives can't win back the working class. Their values have completely and utterly gone in another direction compared to what the average working class person cares about.
The fact that "pride" politics are considered more important than revitalizing "flyovers" Is all the proof you need of that, and I say that as a trans woman myself. I am personally more worried about making sure I don't go into debt than whether or not corporations are trying to appeal to me with rainbows and flags.
