I gave you links that support my argument, very well.
I am not sure what else you want. Quotes from each one, inline?
If you don't have the time to read what I posted, and understand how it applies to this thread, then please copy and paste this thread into an LLM chat bot, and ask for clarity. I just tried that, and even an LLM understood my response.
Holy fuck, Batman. No one's interested in that LLM verbiage. You made specific claims. Claim A:
"Environmentalist groups were in some cases entirely formed by fossil fuel interests."
It's clear from context that you're talking about genuine organizations and not astroturfing. So far you've not named a single one that was "entirely formed by fossil fuel interests."
Hence, pure fiction.
