Activists (try to) do that as well. But it’s much harder to get close to a rich person or their property, than it is to do something in public spaces. They, too, have to see what they can do with their limited resources.
Next, the media coverage is very unequal, as well as reader’s interest. You are much more likely to click on an article covering a potentially outrageous action, than you are to read about something which does not bother anyone. Although you can rest assured, these things are tried and done frequently.
So naturally, to the uninvolved reader, it may seem as if activists don’t do anything but stupid stunts. And naturally, each outsider seems to think they have a much better grasp of strategy and what actions might make sense than the people who are actually involved in these things.
Of course, a particular action can still be silly. I just want to draw attention to biases at play, in general.
And if you really have a much better idea how to do something about the climate crisis, then go ahead and shine as an example. Not only would you author an actually impactful action (which in itself should be reason enough), you could also show all these rookie activists how to get things done. If your example is convincing, you should see less media coverage about inferior actions.
Right?
