At some point, I am not sure when, everyone started using the term “marginalized groups” instead of “minorities”. The change in language matters. What we are talking about, of course, is just people who have characteristics of their identities that are dissimilar from the majority of people in a society; but when you refer to them as “marginalized”, you are suggesting that they have been somehow actively pushed to the fringes, you see? By just using the word “marginalized” you create a whole story about the people you are referring to; that they are oppressed, banished, ignored, overlooked, silenced, and so on; and you simultaneously create a narrative about the majority as being intolerant, narrow-minded, exclusionary, and so on.
These tricks of language bias discourse before it even starts.
