Marginalize: "to relegate to an unimportant or powerless position within a society or group"
Fun fact: "Majority" and "marginal" are not synonyms.
How not to use marginalize:
"No, I do not agree that homosexuals are a 'marginalized' group of people. Any group which makes up less than 2% of the population is definitely a minority."
I'm actually not writing this to poke fun of this person or to ridicule hir ignorance. I'm noting the irony of this particular person running a blog dedicated almost entirely to opposing the Homosexual Agenda yet who is ignorant of a basic word that is integral to that agenda.
Today's Word of the Day is actually a twofer. For, of course, another word exists to describe how an anti-gay heterosexual Christian living in the US wouldn't have to be familiar with what marginalized means.
That word, of course, is privilege.
