I think it's a mixed bag. I've now read that those who post their outrage on facebook are more likely to act, and I've read that those folks are also less likely to act. I think some issues are being expressed through the internet and some are being expressed for the internet and it's not easy to know which is which.
The libertarian police state thrives on progressivism aimed at personal freedom and social justice, which are really important(!) but nevertheless give the system the space it needs to keep abusing while the citizens remain content in their righteous but limited activism and in their self-righteous indignation at their enemy the cretins.
Seriously, drone warfare is one of the most oppressive experiences I can fathom. You literally live in a village and for a year there's just a drone every day doing rounds about the sky, and then a year goes by and all the sudden it launches a rocket and kills innocent people you care about, and then it just sits there, hovering above you like a giant insect, and you never know when it's going to strike again.
But we're okay with that because we're not the racists and homophobes.
Uh, you do realize that drones do not kill villagers due to their sexuality or race, right? They just kill what is around. Death of a villager in Pakistan<verbal attack against a minority. Please stop being racist.
