Any examples you'd like to bring up? It's far more common for politicians to claim to be progressive up until the point of assuming office, only to revert to status-quo business as usual afterwards. Obama is the most famous recent example that comes to mind. Ending wars, closing Guantanamo, restraining police state spying, making college more affordable, and implementing socialized healthcare were all campaign agenda items of his that were never achieved even when his party had a super-majority (most never even mentioned again once he was in office).
This seems to be a statement on the level of "cruelty is the point of conservatism." It's non-serious, even if we pretend that there's never been a conservative policy enacted that didn't deliver it's promised goals. It's noteworthy for how it completely fails to give an example of a conservative city or state in the US that faced and solved similar problems.
Well considering the failure of the SF BOS to effectively address any of the cities challenge yet still get re-elected time and time again (even after showing they do the same things their voters complain about) goes pretty far in backing up that claim. As long as politicians in SF say the right thing, that’s all voters seem to care about.
To add to this, there is little to no evidence that diversity initiatives we see today actually helps diversity. It is a big charade and they attack those who don't want to play along with it.
