I think a big part of the problem is just the innumeracy of the society. So back in the stone age, you stand at the water cooler and the office goof ball comes up with an off the wall take, eyes roll and everyone goes back to work not caring a whit about it. Faced with being able see a one in 10, or even one in 5, ratio is enough for anyone in person to consign what what said to irrelevance. But you have maybe 100 million twits in the US alone and then on top of that you have Romad's Russian and Chinese bot farms pumping the noise and yet everyone still get bent if the goof ball now has a keyboard and elicits the response of 0.1% or 0.01% or some other tiny fraction of what is now a global water cooler. The basic inability to put how tiny the scale of things on twitter really is to the rest of real life seems to confound Americans, and unfortunately especially the MSM who just can't look away.
