People blocked the town because that’s the only way to stop its demolition. Protesting in front of a power plant doesn’t do anything.

Since you brought up the “climate gluers”: When they glue themselves to the street drivers should form an emergency corridor as they are in a traffic jam. Since that doesn’t happen it’s bot the gluer‘s fault if an ambulance can’t get through - and I‘m not making that up, a court judged this way. The protesters block cars, which are a cause of CO2 emissions, and as such their actions are completely validated as their goal is to reduce these emissions.

Regarding „climate gluers“ and protest at a power plant: These people already did exactly that. They blocked airports, closed pipelines and protested in front of power plants and government buildings - with no media coverage at all. But when they throw food on a painting (which is protected by glass and not actually damaged) suddenly people are outraged.

Fact is, protesting doesn’t work - you don’t get enough attention when demonstrating “the right way“ and when you do something that gets people’s attention you are told to demonstrate somewhere where you don’t bother them.
