I’ve met a lot of Scousers over the years. I went out with one for two years.
Most are sound. Many are the closest people to Mancunians in the country.
But there is a healthy core minority who are über-Scouse anarchists, both Liverpool and Everton fans alike. Exactly as you describe there, all following the likes of Tony Evans on Twitter and probably have a framed photo of Ricky Tomlinson (who did have far right wing views in his youth before his big Socialist switch) on their mantelpiece.
I bet it’s frustrating for the sound Scousers.
There are a lot of Mancunians like this n’all, but they don’t come out with “Britain has an anti-Mancunian attitude” whinges.
