I'm afraid that you are onto something here. People misattributing climate change to the poor masses is increasingly common and overpopulation in poor countries is often cited as a reason not to engage in any change of behavior on the rich nations side.
People keep spreading the malthusian myth of overpopulation and shifting blame to the poorest. Blaming the poor while giving the rich a free pass is not only unfair, it’s cruel.
Once climate change denialism is not tenable anymore, climate change will be instrumentalized for atrocities.
