It is all very sad. I have a pet theory on this 'Tate as influencer' thing. My step-daughter is doing a PhD on that left-behind generation of working class youngish men who follow him and so I talk with her about it quite a lot.
My theory (which is probably bollox anyway but here goes) is based on my experience of working alongside loads of lads back in the day who'd now be among these 'left behind' young men who think he's something to aspire to. These lads were labourers, and they worked alongside blokes who'd been doing that job all their lives and had seen it all and done it all. They were hard as nails, really funny and quick witted - and ruthless! Those older guys acted as a brake on a lot of the nonsense beliefs and outpourings of some of the younger fellas. They were in effect role models. When one young 'un came out with some ill-informed crap, what tended to happen was they'd be roundly ridiculed for it by the older men and get laughed out of the tea cabin and he'd have to think again or face being laughed at every day.
Those kind of workplaces are gone. Work is often temporary and liminal and the old guard aren't there. The young men who follow Tate and are in effect his fan base would have been mocked into line back then but now instead, they often work and live together away from home as contractors. They're often around the same age, share the megaphone of social media and what's said so often between them becomes utterly true to them.
