What can we do? Well, again, looking back, probably not much. The liberal intellectuals are always in the minority. See Clay Shirky’s Twitter Storm on this point. The people who see that open societies, being nice to other people, not being racist, not fighting wars, is a better way to live, they generally end up losing these fights. They don’t fight dirty. They are terrible at appealing to the populace. They are less violent, so end up in prisons, camps, and graves. We need to beware not to become divided (see: Labour party), we need to avoid getting lost in arguing through facts and logic, and counter the populist messages of passion and anger with our own similar messages. We need to understand and use social media. We need to harness a different fear. Fear of another World War nearly stopped World War 2, but didn’t. We need to avoid our own echo chambers. Trump and Putin supporters don’t read the Guardian, so writing there is just reassuring our friends. We need to find a way to bridge from our closed groups to other closed groups, try to cross the ever widening social divides.
