I’m pretty sure activists are not just “people who show up to rallies”. Especially not the kind that a megacorp is trying to murder.
the idea that there's no possible way to reasonably estimate the number of environmental activists seems very unlikely to me.
Do you happen to have some sources for a reasonable estimation on the number of, say…
• hackers?
• crackers?
• political activists?
nope. What has that got to do with my comment? Someone was implying that it was impossible, I was saying that claim was implausible. People estimate those kinds of numbers all the time for statistical purposes.
