I think it helps to have a nuanced opinion and make sure we don't spiral into an echo chamber. For my example, I've found that lefties are able to identify a lot of the right problems, it's just that they think gay space communism is the solution to it.
For instance, I completely agree that North American cities are really stupidly designed. The car-centric nature of them means you're stranded if your vehicle breaks down. The fact that you have to go into debt to buy this big stupid box to navigate your own city is ridiculous in the first place.
But when it comes to their solutions for this they can't separate their stupid idpol nonsense from it. My local city government keeps talking about "equitable solutions" to traffic and pedestrian fatalities. Typical "world ending, women most affected" type stuff.
Plus they keep droning on about high density housing which absolutely no one wants to live in. in their utopia we'd all live in depressing Soviet-style block apartments.
I can't think of any "leftist" idea / policy position that hasn't resulted in a worse unintended consequence. Everyone of their ideas requires other people to do things for them. Especially via taxation. It's never a virtue of independence or hard work or self improvement or achievement.
Even the city build / living construction issues results from mass immigration without the resources applied to increase infrastructure capacity accordingly.
It's never actually unintended. They just say it is or too many people will realize they are harming us on purpose and react accordingly.
