I think some of your initial posts might have read as tone deaf. A sentiment similar to "look at the beauty in this tragedy" can feel like downplaying the tragedy, or it can feel like downplaying similar, other tragedies. ("This concentration camp made their space beautiful" can carry the implication that others don't, unintentionally suggesting that somehow the people in this one are better than the people in that one.)

You later clarified, but I suspect there's also a group of folks who don't want to hear that the US had concentration camps.
