No Soup For You. But Lots Of Bologna Sammiches

Two years ago, Phoebe Plummer, 23, and Anna Holland, 22, ‘Just Stop Oil’ cultists, entered the National Gallery in London and threw soup onto a famous Van Gogh painting. They then glued themselves to the wall while ranting about climate change.
"Just Stop Oil" is a cult. It takes impressionable people and convinces them that if they don't break the law and make the lives of other people miserable, life on Earth will cease to exist in relatively short order. Being brainwashed doesn't give a person the right to block streets and damage priceless pieces of art. That's a lesson these lunatics have been loath to learn over the years. I don't know if this will change the calculus for them, but it's necessary nonetheless.
Recently a judge sentenced Plummer to 2 years in prison and Holland to 20 months.
The judge who oversaw the case wasn't kind in his sentencing remarks.

In his sentencing remarks, Judge Hehir said: “Your culpability is at level A. You did reconnaissance and planning and talked to a journalist. Your harm is at category 1, which means extreme harm to society.”
He indicated that conscience was not a mitigating factor and that “The action you took was extreme, disproportionate and criminally idiotic given the risks involved”. He continued “There is nothing peaceful or nonviolent about throwing soup. Throwing soup in someone’s face is violent.”
Addressing Phoebe he said “You think your beliefs entitle you to do anything. I was treated to a lengthy exposition to your political views. The suggestion that you and others like you in a democracy are political prisoners is ludicrous, offensive and idiotic. You have no remorse and you are proud.”

The key phrase there is, "You think your beliefs entitle you to do anything." That is the paradigm these "activists" operate under. The fact that others have a right to go to work, get to hospitals, and enjoy their lives doesn't register with them. Doomsday cults do not care about other people. They only care about their delusions of grandeur.
For context, "Just Stop Oil" is demanding all fossil fuel extraction be ceased by 2030. What would happen if they accomplished that goal? Millions upon millions of people would die, with the highest death tolls being in underdeveloped nations in places like Africa. Fossil fuels power the world. To think that can be stopped in the next five years is absurd and dangerous. If anything, these two women got off easy.
