> The US put japanese people in in concentration camps and most US citizens supported it.
Amazing, your lack of self-awareness. Your deflection and whataboutism can't even let up for a second. In case you need yet another reminder, this thread is about Chinese camps.
> There is a huge difference here. When you say genocide, it is equivalent to holocaust
You are saying this. You. You are pushing the argument to the extreme ("everything is a holocaust") to discredit what is actually being said ("these are mass interment camps with systemic violence and arbitrary punishment"). It's an argumentation technique that doesn't work when the other person knows what's happening.
