I hate the word ‘Consumer’ or I mockingly call it ‘CONSOOMER’. Because that’s to imply everyone in the world is just cattle, but with wallets. We’re no longer customers. We’re consumers now. And a consumer’s purpose is to consume shit, whatever is put out there. Got money? Shut up and consume, it’s what corporate interests and capitalism itself thrive on. Consume and consume.
I think the implication is that the person is thoughtlessly following an ideology, in the same way most people using the term are.
