The world is becoming increasingly divided, with groups holding starkly contrasting and extreme views about all sorts of things. In this country we are perhaps most aware of such divisions arising from Brexit but there are a whole range of issues that attract controversy and debate: nationalism vs globalism, environmentalists vs global warming deniers, the city vs the country, vegans vs carnivores to name a few. In some ways it has always been like this, but perhaps what is different today is the role that social media plays in terms of who we talk to, and where we get our information. Maybe we don’t hear opposing views because we only connect with people who have the same ideas as ourselves? And when we do encounter different ideas we use twitter or some other platform to make aggressive noises.
