Upside/downside to this:

• Upside: Trump followers, in accessing Gab or Parler to read his posts, will inevitably be greeted by pornography, blatantly racist, misogynistic, homophobic, and xenophobic content and imagery, and calls to violence. I say this is upside because I don’t think many of them will like this, and, in fact, it’ll probably scare some of them away.
• Downside: A retreat by the Trump cult into a small, dark corner of cyberspace will, over time, only feed and concentrate the amount of crazy that already festers there. Cockroaches hide in the dark for a reason.
