The person you’re replying to never even refuted the claim about China. Many people don’t know about the 13th amendment, so it’s actually relevant to the conversation. Your weirdly hostile reply isn’t relevant because it’s reductive and misplaced. If you truly cared about forced labor, you wouldn’t be trying to squash conversation about it.

Sure but I think it probably isn’t as easy to gather evidence for this in China than it is in the US. That’s why I think it’s fair to assume the lack of evidence doesn’t mean it isn’t happening. There’s evidence this occurred in collapsed regimes of similar stripes. It’s plausible that China isn’t an exception. I’m not at all suggesting whether this is widespread or not. I have no clue. It could be extremely rare.

No question about the incarceration rates.
