What other methods have these people tried that have failed? How do you measure the success of this method in terms of achieving desired results? Is there data that shows traditional marketing is less effective at achieving the particular aim of this cause; whatever that aim is (because I'm not sure).
In terms of just spending money to stop climate change; do you have data to show that this method is more effective than spending the money on green energy research or other direct funding?
It seems incredibly vague to say that "working within the system doesn't have any effect" but I'd love to see the data that this is more effective than putting ads on TV in terms of actually getting people to support your cause.
I'm not on their side, I don't think it is good.. but I'm really surprised by the non-empathy of many here.. those folks are kind of panicking for the future and imo radicalization if nothing happens will become much worse - this glueing is also kind of little self-destruction, and in the end still a very peaceful protest. And it least gets them attention. And while I have accepted the fate that future generations (if they are there haha) will hate us for what we have done, or what we have not done, in my lazy chair.. and while I would similarly judge those activists for doing some non-sense.. if I'm honest, I have no clue what they should do better. Resigned, kind of. We all know not much will happen. :(
What you do here is really just very top-down distracting rhetoric, imo ;)
The only solution is to target those people directly and make it too risky to do business which is environmentally reckless.
I expect to live.
As for living, perhaps you will - do you think you might wish you weren't?
Gluing your head to a painting cannot possibly be described as an "actual idea".
