You don’t have to sell me on climate change protests. I’ve attended a few myself.
I’m criticizing the delivery, not the message. The majority of people that heard that protest were those who travelled from around the world to see Stonehenge. Their plans were ruined, and they don’t care any more about climate change than they did that morning. Some may even resent the protesters.
Performative radicalism is only compelling to those already behind a cause. It’s discrediting to everyone else, who should be your target audience.
