snarking opaquely about our poor reading comprehension and our muggle failure to grasp the DEEP KNOWLEDGE to which you are privy
Leftists do this about other leftists too. I've been on the receiving end of that on FWR. Apparently the Morning Star shills for ?one of the communist factions? because burble burble something that happened in the seventies or eighties (so before I was out of primary school, if born at all) that might have involved Militant Tendancy and also taking a view of Russia's invasion of Ukraine that isn't "Russia bad, Ukraine good", but of course if Ouroboros was a real leftist she'd know that and would swerve the MS because blah-wrong-kind-of-leftists-blah.
And I'm like, I can agree with the MS about women's sex-based rights and I can strongly disagree with their overly-sympathetic stance towards Russia whilst also understanding that that particular conflict is a lot more complicated than “Russia bad, Ukraine good" and MS's letters page is one of the few places where that complexity can be discussed freely. And I don't give a shit about stuff that happened whilst I was still in nappies because the people involved are probably dead or retired by now and the organisations involved will have moved on. But this is all deep knowledge that I'm not a true leftist without, apparently, even though I've read "The Origin of Private Property, the Family, and the State" from cover to cover.
My point is that this is a leftist discrediting tactic, because what they allude to often has no evidence, but is the "oral history" of a particular faction or factions. So if you weren't there at the time, or haven't picked it up from the rumour mill, you won't and can't know, but they use it to discredit you anyway.
If you are disabled in a way that makes meeting people hard, you are really vulnerable to this tactic, because you don't hear the rumours.
