Interested in Language
In a discussion with a friend I wanted to make the point that he shouldn't generalise about people from different countries and call them all using the same, collective term. Can I say "you shouldn't bunch up all those countries into this generic 'South Asian' term" ?
If not, what word should be used here? I'm looking for a word that would mean, "aggregate into one generic category in an unnecessary, superficial way". But also, a word that is colloquial rather than formal i.e. "generalise" sounds a bit formal to me.
