I probably agree, but I'm not quite sure what you mean. Do you mean that people who are in a disadvantaged group in a society are more sensitive to language that is biased against their group? So women notice (and can be offended) by phrases like "you throw like a girl" while men might not care, or even notice, that it's sexist.
Or do you mean people in disadvantaged groups are, in general better at detecting bias in language? So, poor people are better at spotting politic bias in reporting?
