To be fair, where I previously lived I was arguing for Remain ("boomer" who is fed up of the "it's all the boomers fault" like nobody of any other age voted Leave) because the majority of local Muslims were voting to keep the Poles out! Being opposed to immigartion is not just a "white thing", as the number of non-white members of Reform shows (and there's quite a few - they have been out on our streets canvassing for months in this area).
That said, whilst I agree that many people do not understand government in the UK, where decision making lies, etc, it is the usual misinformed "blame the voters" rhetoric. We teach very little about government, voting, or even rational and critical thinking in schools. If you do not teach young people the skills they need to make reasoned choices then you create adults who cannot do it. These skills do not spring fully fledged when you get the vote. Schools teach compliance, not questioning - and so do many parents. If you don't like how people are voting, then look to where the blame actually lies - with how we bring up and educate children.
You can also blame the political parties - they were also mainly campaigning on national issues, certainly at national level. Labour and Reform, for example, with their ads about the NHS - a matter not controlled by local government.
Politics has become about soundbites on media, rhetoric without any grounding facts. Political parties have deliberately dumbed down politics. I recall standing on doorsteps in my youth arguing for policies. Nowadays it's six words on Insta. Around here the only party on the streets - as I said, for months and months before the elections - was Reform. Their politics may not stack up but they put in the effort and they were seen and engaged with people. People who were terrified after losing winter fuel allowance, and faced with cuts to their disability benefits.
Repeatedly Labour voters, were telling Labour that they felt betrayed and scared. And even after a trashing in the polls, Keir takes this as a message to "go further, faster". Voters may not always understand, but they send clear messages, and "further, faster" was not the message. And actually the clearest message is not from those who vote. The majority can't be arsed to vote. That's the clearest message...
