You or I could run this test right now on Facebook. I suggest you just post a comment somewhere you in Facebook that you want some person or some group of people to die, it doesn’t really matter who, and measure the amount of time it takes for someone to flag it and have it deleted. This is just low hanging fruit, and completely unrelated to the immediate issue at hand.
My guess is that the original poster is leaving something out in their comment and the post wasn’t as brazen as the comment suggested.
I meant, you could actually execute the experiment yourself and see what happens. You don’t have to trust me, rather just do it and find out how quickly your comment is nuked. You won’t get into any trouble other than your comment being deleted…probably. The truth is easy to discern by just running the experiment if you want, but I’m guessing you have some cognitive bias that you’d rather have confirmed instead?
Anyone could say exactly the same thing about any hot-button topic and feel as self-righteous as you. Again, it's fantasy until you back it up with something empirical.
The experiments are straight forward if someone wants to run them. But your fantasy is backed up by as much evidence as mine, we are arguing about whose anecdote is better until someone does the experiment.
