I kind of agree in the sense that (in my view) preventing Australians from watching the US execution is a kind of a fridge issue - possibly a distraction from more important issues, possible a unnecessarily divisive position for The Greens to take. (Probably most people agree that broadcasting the execution is bad; but many people are sensitive about censorship.)

So in that sense perhaps it is a politically unsavvy thing for The Greens to take a position on. But on the other hand, saying & doing stuff like this is what gets them into the media. When The Greens are only talking about pencil-pushing bean-counting by-the-numbers sensible policies on core issues - they are simply ignored. A few people nod and say ‘fair call’, and no one says anything. No one spreads the word. And so very very few people hear anything about it. So when The Green stick to their core message, they just don’t heard. So these little provocative foraying to side-issue end up being pretty much the only news many people hear about The Greens at all.
