I know how you feel. I dread a Labour government.
People forget how hate-filled and destructive the left can be. Listen to a stand up routine by Frankie Boyle, for example. My partner is a big fan of Boyle (who describes himself as more left-wing than Chomsky), and so I've seen many of his shows. Like so many on the left, he seems to be motivated by bitterness and hatred, which he disguises as sympathy for the poor. Socialism attracts such people. It's perfect. Not only does it tell them that their failure and unhappiness isn't their fault, it's 'the system', but it also promises revenge. Just wait until the revolution, or until we gain power, then you'll see. Of course, they don't use that language. They talk about 'justice' instead.
The left have this vague enemy, onto whom they project all their bitterness and hatred, and who then becomes the target for their spite. A lot of people who vote Labour are actually despised by the party itself. If you are mildly patriotic, middle(ish) class, own your own home, read the Daily Mail, don't want houses built on the green belt, resent people who exploit the welfare system, and think immigration is out of control, Labour are not on your side. You might vote for them, because you think we need a change, and because you consider yourself moderate and reasonable, but you'll get a government that hates you.
Take house-building as an example. Now it's true that we have a housing shortage, and obviously people need somewhere to live. But having talked to left-wingers, I get the impression that what they really want to do is not provide the poor with somewhere to live, but ruin the lives of middle-class NIMBYs. They love to imagine some middle-class couple having social housing flats built on the field next door, ideally with a few 'problem families' whose kids terrorize the neighbourhood and ruin those NIMBY's lives.
Immigration is another example. Any sane, rational person can see that these boatloads of fit young men are undocumented migrants, not refugees. Refugees tend to be women, children and the elderly. If you allow tens of thousands of undocumented young men into a country (many of them, no doubt, criminals fleeing the police), it's going to cause problems. But the left welcome those problems. So long as it upsets the Daily Mail NIMBYs, that's enough.
Another example is cancel culture. I don't believe that the woke left really care about 'offensive' passages in a Jane Austen novel. When they demand Austen's novels be removed from schools, or that passages in Roald Dahl's books be re-written, etc, what they really enjoy is upsetting their fans. Same goes for vandalising statues of Winston Churchill. They don't really care about some remark he made in 1927 (probably taken out of context). They just enjoy seeing the horrible Daily Mail NIMBYs getting upset when his statue is covered in graffiti.
I remember Roger Scruton saying that he was in Paris in 1968 during the uprising. He was left-wing himself at the time (I believe) and so mingled with the crowd asking them their views and so on. When he spoke to the students involved, all he got back was a load of pseudo-intellectual Marxist gibberish. And it suddenly dawned on him that they weren't really interested in politics at all – they were just enjoying smashing windows and upsetting people. That's the left in a nutshell.
