A major problem is also that progressive messages are complex, and don’t offer easy answers. They require that people engage, and put in a great deal of effort… that will mostly not bear fruit for them, or their children, or their children’s children… but will help over time.
But people are exhausted. And sick of waiting for things to get better… so they fall prey to the easy answers. Which is what the far-right offers. Easy answers and excuses for why everyone else is at fault.
Part of the problem is that people only want the easy answers. Which is not an easy fix. It requires convincing them of the lie of easy answers.
