I really think much of this narrative is induced by the current government. Many are absolutely broken hearted by how far the UK has sunk, since 2016 but, most recently, under Johnson. I come from a Labour voting family, I have always voted Labour (Lib Dem in European elections around here), my dad is a fierce Labour supported. Even he would say that there have been some decent senior Tories over time - Heath, Heseltine, even Major (though ineffective as PM). He couldn't bring himself to 'hate' any of them, because they were largely respectful, 'one nation' Tories who held their office with seriousness. He may have disagreed with many of their policies, but they didn't govern with hate and impunity.
Recent politics has given rise to intense feelings, more so than at any time since I turned 18 and was eligible to vote in 1997. This government under Johnson attracts the worst of the far right wing. They have behaved utterly appallingly in power and presided over what many believe is the worst political period in their history. Lots even believe that Johnson et al are worse than the Thatcher era.
Do I think that all Tory voters are as the op describes? No, of course I don't. But having seen the amount of damage - to individuals I know, to the less well off, to society in general, to politics itself - that has been inflicted on this country in the past 12 years, I do find the 'anyone but Labour' mentality infuriatingly opaque to comprehend. Labour have been in power for a fraction of the past 100 years, I simply do not understand how anyone could look at Johnson's government and believe they've done a good job.
And so, we see the kind of strong emotions articulated by the op. And we see the predictable inflammatory responses. We've been successfully pitted against one another - normal, friendly, law abiding, tolerant people engaging in the politics of hate, disrespect, intolerance. Johnson has done this, and he has surrounded himself with similarly awful people from Reece Mogg to Nadine Dorries.
Don't get me wrong. The anti-Starmer brigade seem equally intent on keeping the Tories in power and I am equally frustrated with them. History tells us that most people are centrists by nature. Centrist parties do well with the electorate and tend to promote more unity than those who lurch to the left or the right and create division. There's no such thing as 'perfect' policies, just 'best fit'.
I've met some lovely Tory voters in life, many are friends. Even they are turning away from this government, having seen their behaviour in power.
I don't dislike Tory voters. In the current climate, I simply don't understand how they can continue to prop up this immoral and corrupt government. And yes, it makes me angry as he'll. And those are the perfect conditions under which 'othering' and alienation thrives.
It's all such a massive shame for the UK. It's a horribly unsettling time.
