I've had some conversations about the cancelling of everything Russian and people are like, "eh whatever, war bad, it's fine." They don't actually think about it.
My experience is people who were all pro-Iraq war, WMDs, pro-torture. Generally lack any hindsight or even process if they were wrong or know what they thought at the time. They have just moved on.
A friend of mine who I used to get in arguments over Iraq, WMDs, torture etc. Did admit he got the WMDs and the war wrong. However he's now all gender is a social construct, orange man bad and some woke stuff. So we have sometimes gotten into arguments again over that. Which was shocking, because I honestly don't know where peers of mine got indoctrinated by the woke shit. None of it was in schools or high education when we went through it.
