Yeah but by the time you get that far into the convo they've already convinced themselves that you're just bullshitting for daddy Xi pooh bear or whatever the fuck and shield their brains from introspection while they jump straight into "But the Uighurs!" and now you're a genocide denier to the audience if you continue arguing. It's like the perfect liberal trap. The only people who will seemingly consider what you're saying that far into the conversation are people who already agree.
