What you're describing is our national problem. People are more aligned with either extreme than they used to be (likely due to the internet exposing people to echo chambers), and are less tolerant of "giving the enemy a win" by collaborating to do SOMETHING. So stasis and hate are the outcome.

Example: I agree with Republicans on some things, like prosecuting thieves which my local (Seattle) Democrats don't care about. But if I were to publicly state my interest in anything right-aligned, my peers would round me all the way up and think I hate women or something.

I'm not really describing a national scenario, but some NYC specific conditions. For example the much vaunted AOC has personally intervened to kill 2 redevelopment projects that were broadly supported by neighbors and local community boards by whipping local DSA activists up and threatening council members and bringing the NIMBYs out who were already against any new development.

Rikers is another example where the prison abolitionists are coming together with law and order types who like Rikers. It makes no sense for these leftist prions abolitionists to partner with MAGA types in Staten Island but here we are.
