Unfortunately it's also only a matter of time before climate change gets worse - we've already seen what's happening in the northern hemisphere. Regardless of who is in the road or what work you need to get to, hitting and carrying a person on the front of your car or assault deserves charges, especially as the cops cleared it in ~15 minutes anyway.
Saying that - protesting is also meant to get people on your side rather than just raise awareness. This one didn't.
So you believe 15 minutes of delay justifies assault?
I mean, if you want to go that path carbon emissions is fucking with most of our livelihoods and its also a known, direct correction. Does that mean I can deck every tradie in a ranger?
