Some time ago at another message board I disputed a young liberal whose argument was America started the war with Japan, not the other way around. I assumed he was one of the more loopy liberals until lots of other college-aged libs with the same “America started the war” theory piled on. I linked to Wiki’s listings on WW2 but that was a “narrow view of history” and “history was written by the victors”.
So I asked how they thought America started the war with Japan, and none of them could agree on details. What they did agree on, was that we were racist warmongers since Plymouth Rock and that the Japanese were another race, our use of nuclear weapons was the mother of all cross burnings, and that was about it.
My impression was that more than half of them didn’t even believe what they were saying, but that truth didn’t matter anymore...like truth itself is racist if it stands in the way of our Bataan death march to socialist utopia.
Usually, ‘the US started the war with Japan’ crowd cites the US (and allies) cutoff of most of Japan’s oil supplies as the key. The US had long sided with China over Japan as the Japanese demands on China dating to before World War One. This theme is used by thoughtful free-traders even today.
I think you are right, that some liberals often disagree with one or more liberal lies... But they have to participate in the lie anyway, to support the “good guys”.
