My premise is that they don't matter.
The LG etc crowd gives a ton of money. They are a big part of the media (at one point 3 of the 4 major network anchors were gays). Matters in the big city and the sheeple Dems follow their leaders. They’re also fond of calling Republicans homophobic (a fake, poll-tested word), so that’s boomeranging on them.
This is using “Rules for Radicals” against Democrats: make the other guy live up to his stated beliefs and expose him as a hypocrite.
We also want to fracture the Dems. Make Mayor Pete’s supporters say they’ll never, under any circumstances vote for Bloomberg. Divide and conquer.
Exactly why we need to get the Bernie Bros to not accept a stolen nomination.
