And time. You know, because time spent with other organizations is what we're talking about here? It takes time to fight a criminal charge. Besides, we're now nitpicking about how much time they'll spend in jail, rather than you proving with any evidence that they're doing anything more constructive than performative stunts. Rather than show actual good they're doing, you've just supposed that they might be doing it, and challenged that I can't prove that they don't. I hope you see how ridiculous this is.
You and me are arguing a non-provable hypothetical. Yes time they spend in jail is time they aren't doing anything productive. That doesn't mean they don't do anything productive in their time they do not spend in jail. Also: The repressions they face as a consequence of their activism is part of the activism in my book.
Every second we spend on this stupid conversation is a second that proves the effect of the protest is to make the stunt the subject of the conversation, rather than the climate.
I'll argue that without that stunt we'd be talking about something different entirely likely unrelated to the climate crisis. Which would be even less helpful.
If the protest accomplishes their goals, then why separate them? Why have a separate organization at all? What's the point of that?
As I have explained already: it's about communicating to the public. Doing things under a certain name helps the public associate the current actions with past actions under the same name. If you do two vastly different things it helps to separate those by name too, otherwise it can get confusing for people that are not interacting with your group often enough.
No, activism doesn't need to please people, it needs to be targeted to inconvenience the right people.
If I show up at your home first thing in the morning and pour colored powder on the car you use to get to work, and I tell you "I'm helping spread the word about starvation in Africa", you're going to wash the powder off and then yell at me for being a fucking idiot and taking it out on you. You're not going to stop what you're doing and send a donation to feed children in Africa because I vandalized your car.
That's quite the strawman you've put up here. I'm not advocating for bothering random people at their home and that's not what JSO is doing. As far as I can tell they are targeting people of public interest, big events, and popular public places. Which is the "right" people because the climate crisis is about all of us. We all are contributing to it be it daily choices or our choices while casting our democratic votes.
