"The sniper community." For years, I've been following the overuse of the word "community." Not everyone who can be put in one category (e.g., gay) is actually in a communal relationship with others in the category who may, in fact, commune in a group. (You could feel sad and left out if you were something that gets called a community but didn't have any rewarding group experiences.) And not every category that people can be put in is the sort of thing that suggests the relationships of community. I remember hearing the expression "the military community" about ten years ago and thinking, now, the use has reached its most ridiculous extreme. Today, on Morning Edition, I heard the most ridiculous one ever, in a story about American soldiers trained as snipers. One of the soldiers referred to "the sniper community." Next up: the loner community.
UPDATE: Chris notes that the most profound misuse of the term "community" is the expression "the international community."
