Its an interesting issue. I agree with their position, I also believe the govt/police have gone OTT on them which if played correctly, could have gotten them a sympathy vote. But they are instead coming across as hippies (and I want to make it clear coners are not hippies, we wouldn't break bong with these tight arse ferals. They ruin our image).
But I agree, not much you can do these days to get air time without being a pain.
As I see it, disruption only causes real change if it directly causes real change. For example, if you want to really stop climate change then you kill half the earth's population Thanos style.
As that's not an option, your only chance is by winning hearts and minds.
I mean, you have over 99.999% of climate scientists telling you that anthropogenic climate change is a major issue, and in response you have a large portion of the population saying, "Anthropogenic Climate Change is a hoax!"
Meanwhile when you enforce vaccination you end up with a record number of anti-vaxxers.
No amount of truth will change their stance. The only way to turn people is to make them allies.
