However, even terms like "modern day" to describe "concentration camp" are inflammatory, inappropriate, or even harmful as they may minimize the severity and unique historical context of events like the Holocaust. You're making a weak distinction with no real difference. "Modern day concentration camp" does not imply that it's a "lite-version of a Nazi Concentration Camp". Instead, it's obviously intended to convey the message that the atrocities that happened in Nazi Concentration Camps are happening RIGHT NOW in "modern days" and that's simply not true.
When people realize that it's not actually like a Nazi concentration camp where people are being murdered, executed, cremated or bulldozed into mass graves... they they'll assume that all the other screaming and shouting is just as ridiculously hyperbolic and they'll ignore that too.
Sure, I get that the implication is that the current situation being referred to shares some similarities with historical concentration camps... it's NOT actually a concentration camp.
