Is communitarianism a "real word"?

From a forum today at the Columbus Dispatch:

Yes, I have 2 degrees. Proud of 'em - I worked hard to earn them. Not even a scholarship.

I don't want children feeling guilty because their parents are unable or unwilling to supply what they need to learn. It's not their fault - let them feel guilty for their own bad choices.

You didn't spend time and money "supplying" me with anything - I earned every penny (emphasis on "penny") I made.

I didn't have time to "train" kids to be group thinkers or COMMUNITARIANS (hate to break it to your uneducated self...not a real word)- I taught kids math, reading, and history. I didn't have time to worry about leftist philosophy what with the schizophrenics, crack-babies, adhd kids, and kids who had never been told not to hit their neighbor during an argument.
