Yes, it's horrible. People feel free to make comments they would never have made even 20 years ago. I see it all the time on local Facebook groups - comments about 'boat people' and things like 'It's always them' on crime reports featuring non-white people.
It's social media. People are consuming propaganda constantly, from Farage, Tommy Robinson, GB News, and all their hideous offshoots. Watch one video and the algorithm sends you 10 more. There's a hell of a lot of money going into it, the same as happened in the US before the last election. The goal is division and hate, so that the far-right will get in at the next election.
I hope we're better than that as a country, but I'm less and less hopeful.
