Democrats are working to frame some of this year’s elections as about Charles and David Koch. As Peters and Hulse report in the New York Times, these billionaire brothers are spending a lot of money to influence elections across the nation.

Mr. Hulse’s interview with On the Media discusses using words like un-American to describe the Kochs and collectivists to label progressives.

The word un-American should be used sparingly, if at all–especially when describing a person. Unless used very carefully, it’s name-calling and probably attributing evil motives to someone who doesn’t mean harm.

I do think that some behavior might be considered un-American, but because people have different views of our country’s interests and values, that’s also tricky. It’s best to avoid the word.

Do you think it’s appropriate to label people as un-American? Is there such a thing as un-American behavior? Why or why not?
