Same in my case. Father, radio operator on merchant ships, torpedoed & sunk in the Indian Ocean, blasted in the North Atlantic convoy runs. He never talked about the war other than to say both sides had to do their duty because of those at the top seeking power. In fact he was incredibly grateful to the commander of the U-boat who ordered his men not to shoot at the crew who had managed to get into the lifeboats.
Mother spent 4 years at Bletchley Park - again never talked about the war or suggested she had anything other than respect for people from other nations. (A brief aside - she met Churchill wandering around the gardens one day at Bletchley park & he started chatting to her. He asked her what she was working on. She responded "Sorry sir, I can't tell you, it's top secret!".
I shouldn't speak for Quill , but I don't believe Quill is suggesting that at all. I believe he is alluding to internal "British" resentment between a small percentage of older generations having been aware of ancient "royalty" led atrocities against the countries that eventually became part of Great Britain, and vise versa. He most definitely said that there is a lot more acceptance/tolerance now in the most recent generations. A good sign indeed. But hardly surprising older generations had less trust in their leaders. Only minorities as Quill said, but they manage to get a lot of press.
