stops climate change from getting even worse, killing even more people, destroying even more property and causing more mass migration, causing even further ecological collapse

And what is that going to solve exactly? What is it that this is a “solution” to?

Yes.

Only 75%?! Paradise!

anti-democratic means

Protest is democratic.

other climate activist groups

What other climate activist groups?

regulating the most destructive industries and forcing them to stop releasing greenhouse gasses

And what is that going to solve exactly?

Indeed

There are solutions

Such as?

we are all in denial about the climate crisis

LOL speak for yourself!

It was obviously asking about what comment the politicians have made

Why would you assume that? It was obviously asking about what comment the protesters have made, from the fact that they were asking about whether “they” had commented “on the reason for the protest, or just the act”.

It depends on which “them” is being referred to in OP’s comment. Assuming “them” are the protesters, then the answer provides what the protesters said, or at least what the organisation they represented said.

Uhh…

Did any of them comment on the reason for the protest, or just the act itself?

Pro-tip: if you have questions raised by an article’s headlines, read the article.

“Just Stop Oil said the motivation behind the incident was to demand the next UK government end the extraction and burning of oil, gas and coal by 2030.”

One could argue that Stonehenge is an icon of humanity’s pre-industrial, sustainable origins and as such acts as a reminder of the future that humanity will face after the ecological and civilisational collapse currently underway as a direct result of oil production. And hence Stonehenge is something to do with oil production.

they should be concerned about acidic rain caused by air pollution. But you don’t hear much about that, now do you?

they’re playing a silly game for attention without caring about the consequences

They’re playing a silly but very serious game for attention, the same silly game that politicians and corporate PR departments play. And the protesters seem to care a very great deal about the consequences.

What would you have them deface?

Prime Minister Rishi Sunak condemned the incident as a “disgraceful act of vandalism”.

Not as disgraceful as awarding oil drilling licenses to companies your family is invested in.

Leader of the Labour Party Sir Keir Starmer said the damage

There is no damage: ‘Just Stop Oil said the orange powder paint was cornflour and it would “wash away with rain”.’

was “outrageous”

Not as outrageous as forcefully replacing local Labour candidates with your own choices.

and described Just Stop Oil as “pathetic”

Not as pathetic as Labour’s climate policies.

You’re not making any sense.
