The Labour party admits, itself, that its main voting demographic is now young, university educated big city dwellers. This is the demographic that has totally embraced American style Identity politics. The whole class based outlook & policies of the traditional left are cast adrift, as many working class communities no longer see the Labour party as their natural home.
That's a pressure group, not a party of government.
It's also worth noting that kids grow up, and don't generally take their views with them. The boomers were once doing sit-ins in universities, too. There will never be enough of them to win - thank God, given their solipsism and inability to understand that they are privileged as hell, which is why they obsess over what precise label to append to their sexuality and gender identity, while women are being beaten in their homes, social mobility is almost non-existent, rape's been effectively decriminalised and skilled manual trades lost to an unskilled service economy... all as we head into the most terrifying of global recessions, with climate change up ahead of that.
Bunch of self-indulgent wankers, fiddling as Rome burns. What a crushing disappointment that party has become. They're leaving the Tories without any opposition worthy of the name. Right now, we'd probably have to hold our noses and vote Tory, just to keep Labour out. Please God let Starmer sort it out, and remember that they could actually improve lives, if they just started acting like adults instead of the Red Guard.
