I think it is a case of monopolising suffering. Like the black monopolisation of slavery, this is a monopolisation of the concentration camp. I don’t think using the camps works in this situation because nobody would dare claim Trump intends to murder all the inmates. Of course it is dreadful, as was the incarceration of British troops in the Far East under the Japanese and the Japanese concentrated in camps in America during WW2. As for who has a legitimate claim to say how the Holocaust narrative should be used, I would imagine that ‘where you have two Jews, you will always have three opinions’ will always hold true.
