The disruption thing I have some experience with. I worked a little with the ISO in college since they were the only game in town. I was at a meeting where they wanted to go disrupt a local Green party event. They didn't phrase it like that, they were saying we should go to their event and try to sway them into joining the ISO with pamphlets and papers.

I asked why we should do that instead of just joining them and the organizers seemed super confused. Like there was no possible way we could work together if they were still the Green Party and we weren't. One guy there called them Stalinists?

I should also mention everyone involved in this was like 21 years old at maximum and I was 18. So for years I just thought we were dumb kids until I learned that kinda thing is common
