There's quite a bit of insight in this article, and I'm not going to dismiss or directly comment on any of it.
In my mind, there are two pretty straightforward, first principles at work that underlay a lot of these items.
Many, if not all, negative emotions, at least while being experienced, directly diminish cognitive capabilities. A concrete example: when a person is angry, that person is more stupid.
Next: modern communication technology allows/facilitates/encourages negative emotions to be generated, travel widely, and 'stick' in the minds of more and more people.
As I said, there's a lot of good analysis, but I believe that these two simple things are the most responsible for 'stupidity expanding'.
I went out of my way to state these things briefly, because fundamentally I think they are simple. At the same time, there are mountains of nuances and relevant conditions surrounding them.
