Honestly they seem kinda useless to me. Today, they blocked a bridge which just fucked a bunch of normal people over. Everyone I talked to who was affected by it just said it pissed them off and they've now got less interest in XR.
Aside from that they're blocking construction of a high speed rail, and failing miserably. Bunch of builders have to deal with them playing their bongos and climbing trees by the construction site. Feels ineffective.
I see them as modern day suffragettes, which I weirdly admire.
I don't see any of them doing anything close to radical things like what Emily Davison did.
