Here in the UK, we're going through a phase where right-wing middle-aged men are dismissed as "gammons" and progressive young people are dismissed as "snowflake millennials". People that don't buy into Brexit hype are remoaners, people that want to nationalise services are commies/marxists/trots, people that think the free market would be good for the NHS are neoliberal scum, people that are uncomfortable with current immigration levels are fascists etc... . All in the service of categorising and not having to apply any real thought or empathy.

I don't know if it's significantly worse than the situation 50 or 100 years ago, but it does get on my nerves.
