EDIT: To make my view clear here, Facebook and others are free to remove the videos, I'd prefer if they age-gated and put a warning on them instead, but that's their choice. What I don't like is the way that that some police agencies have been suggesting that mere possession of the video is illegal.
The worst part here is that the attacker himself was suggesting that by hitting on ideas like free speech and the right to bear arms he'd be able to "accelerate" the deepening of political divides. I do not want to be put in a place where I'm forced to choose between fundamental rights and respect for entire races of people, but at this rate I fear that decision time may be approaching. Given time I hope cooler heads will prevail.
But now that some political power that we don't like is emerging, well, a lil censorship never hurt anyone huh?
This very discussion forum is moderated, and very well as far as I can see. Do you think it would somehow be better if the mods weren't here?
It gets morally messy when you consider scale. At what point does it cross over from reasonable moderation to censorship? If Facebook were a country, it would the largest country in the world. Is it okay to censor two billion people because Facebook is not an "official government"?
I'm not against moderation at all but at a certain scale does it cease being only moderation? I would argue yes, but at what point? That's trickier to answer and I can't really say I know.
