Greenpeace, OWS, ELF, Activists at Standing rock and in Briton groups like CND (look up Mark Kennedy) have all been infiltrated and lead astray. But this group is somehow different? I call bullshit especially after seeing these groups piss off more and more people every time they make the news.
This doesn't bring any of this to forefront of peoples minds. I'd argue it does the opposite of what you propose. It forces an association between the topic and people who are not appealing.
You should really evaluate what you're saying here.
Those who do nothing but complain about climate activism were never going to do anything useful and so their thoughts on the methods are frankly irrelevant since the methods work for those who actually want to act.
This issue hinges entirely on getting voters to care. Yet, many groups and even you seem to dismiss them, saying "they don't matter." In reality, voters are the most crucial factor.
It makes sense that the idea of alienating the general public from climate action might be intentionally promoted by well-funded and organized entities. These entities have the resources to influence groups, and we've seen this pattern in many movements since the beginning. Their goal is likely to disrupt and weaken the effectiveness of climate action initiatives.
