I don’t think so. There are so many fronts on the war on bigotry and little progress has been made in 100 years. This feels like an innate property of human beings and humans will always be easy to manipulate to make them hate those that look a little different. About the only practical thing that might help is we criminalise bigotry that might damp it down a lot but people will still behave in bigoted ways they can get away with.
Looks like the story of the night is going to be not that Labour gained lots of votes but that Reform has split the Conservative vote and collapsed their vote as a result and its gifted Labour a lot of wins. Lots of tactical voting has led to the Lib Dems gaining a lot of seats too.
Reform has gained enormously, the Greens and Lib Dems less so.
