Yep, there is a blanket assumption that "old people" (sorry for the generalisation) universally voted leave. However I spoken to a couple of people who REMEMBER the war who whilst being very conservative in a number of ways voted remain because of the war..
I'll check out the LSE research, because it's what I suspected all along.
The irony of citing WWII for populist "leave EU" means isn't lost on anyone with either half a brain cell of those who witnessed it.
I wish my Grandmother was still alive, she visited Germany before the war but during the rise of Hitler. She witnessed unbelievable things, a Jewish women beaten up in front of her in a restaurant and turned down a visit to a Nazi rally.
I'd love to talk to her now.
If you Google the research, you'll probably find it. It came about because researchers had the same gut feeling that you did - that there was a big difference between the 60-79 and the 80+ age groups.
My mum (nearly 90) voted Remain precisely because she remembered the war.
