Yes you did make the claim. It's right here.
When Doomsought said behind the Iron Curtain and Death Camps... I assumed he was talking about Gulags of the Soviet Union and you replied we did that "to an extent" in Vietnam and Afghanistan.
Then Doomsought accused you of Historical Revisionism and cited by term the Soviet Gulags and Chinese Prisons in Xinjiang imprisoning Uighers.
And you responded:
"No, we just did Gitmo, Abu Ghraib (Tbf, Iraq War here but you get the point) and CIA-funded death squads that murdered women and children;"
So yes, you did make those claims. You might not of intended to make that equivocation and to you the difference between a million or thirty million in a Gulag or Relocation Camp to several hundred Detainees held in Gitmo for upwards of twenty years and downplaying that away as "getting into the finer points" but there's no other impression to gain from your post. If there's a failure in relaying your actual claim, that's on you. If you want to shift the goalposts now by stated someone is "getting into the finer points" that's fine, but you still made the equivocation that they were basically equivalent. It's "fine" if you think they're basically the same or that you were just engaging in hyperbole, being dishonest or made a mistake, just don't act like you never made the claim. Your lack of "finer" posting is on you, not me. Sorry.
No this wasn't the point of contention. Doomsought quite clearly clarified he was referencing the Gulags and Uigher population of China as primary examples. You were the one who shifted the goalposts... sorry... "getting into the finer points" of Vietnam and the Soviet Invasion of Afghanistan and claiming the former is basically the equivalent of the Soviet Gulag system.
