So would you say they vote Labour out of habit?? (perhaps because their parents did?)
Rather than because they particularly want to see more a more socially just, and fairer world?
Thinking back to my own political journey, when I left home for Uni (1992) I had grown up in a house that voted Conservative and been to public school. My perception of labour was that they wanted to remove assisted places and tax the crap out of everyone. There was also the background of the last labour government having caused strikes all over the place.
At Uni in my gang of friends we had a chap from Darlington who was staunch Tory (member of the young Conservatives) and another chap who was staunch Labour. Usually after pints, some sort of argument / debate would ensue, and as the YC knew his stuff, the L supporter would usually lose the argument - he just voted Labour because his parents had voted labour but hadn't really thought about it. At the same time I made some other friends who really liked just chewing the fat, talking about anything - and in particular one friend who enjoyed playing devils advocate (regardless of the debate). Through him I learned a lot about justifying your thoughts and challenging what you actually think you know.
After uni I became more and more interested in comedy, and in particular satire. Started reading Private Eye, and this again has encouraged me to challenge what I think. In the area I live, Labour don't have a chance, and I'm still not mahoosively left wing. I'm more middle of the road (as I think are probably the majority in the country that use a brain). But still, I'm one of those people who looks at the policies and the people. So whilst I'd like a more socially just and fairer world, I don't subscribe to some of the apparently egalitarian policies which would disenfranchise people unnecessarily.
For example, I don't believe that Private schools should be closed down and I don't agree with the removal of assisted places
unless there is already something in place to offer those pupils the same level of education. For example in Finland there is no need for private schools as class sizes are 20 and schools are very well resourced. We can't do that straight away, and both of my children have benefitted from smaller class sizes and on site medical care. I had an assisted place. Removing opportunities for children with additional needs or who are neurodivergent etc isn't a positive - it seems unnecessarily reactionary and "screw the toffs".
On the other hand I also vehemently disagree with the current Tory policies of breaking international law, screwing the country over, shipping people off to Rwanda etc. I don't see these as being even half way good Conservative policies. If Conservatism is about good economy, sound finances etc we should be opening up trade and borders, reaping taxes from those who want to work here and making it easier to do that.
