It's not a "damaging narrative" it's the real situation. It's not about expecting protestors to have the answers. This idea it's just stupid people "not listening" is frankly idiotic. It doesn't matter where the answers come from, no one can do anything if they aren't there.
This is the problem with idealists on the left - they are convinces if only people do certain things, their goals would be achievable, and the little people negatively impacted are worth the sacrifice. And usually the things they want done are foolish nonsense that won't work, or will have other horrific results.
Getting rid of oil means ramping down the economy, and also consumption generally, really significantly. And agriculture. I don't get the sense you have any clue how huge that would be, or what the outcomes would be.
So when, under the scheme you are proposing, next winter, you have the economy crash, people can't buy much in the grocery store, fill their cars, and heat their homes, how is that going to work? What's going to happen to the government who puts that through? What's going to happen when banks can't pay interest on investments?
We've had a very minor shadow of what that might look like with COVID shutting down the the economy. It would be far far worse than that.
You realize that is also a direct choice to kill people?
The other factor is that this is a global problem. The UK can take these measure and it will make no fucking difference if the US, Cina, and India don't do the same. How is that going to happen?
You are essentially screaming like a child that people should take action when the effects will be terrible, and then accusing people of not caring and being stupid. It's probably about the best way to get them to ignore you. It's such an own-goal, but I guess no surprise from people with so little;e actual political nous.
