Sounds like you go with the conservative view, that conventional authority has to be made more effective, rather than overturned. You claim it's all down to just opinions which are not rooted in anything physical, but you don't accept when someone who works with physical systems informs you that everything is connected with the physical.
Someone like me, for example. So I fit your definition of a revolutionary, just because I am telling you nature has rules we must obey, and because we have not obeyed for a long time, creating and choosing our own system of energy slavery over the rules of nature, we now have a burning planet.
If you want the planet to not burn any more, we have to create our way out of it, and I mean reverse entropy, like all plants do, and all things living within the constraints of plants do.
We can only do that by stopping using energy extracted from the planet, and that means stopping profit.
You'll probably read this and see it as all an idea - my idea.
But it isnt, ' it's observation of nature, physical reality.
And now it's existential.
What do you think of that?
