Yes. Just like you are. It's called commenting ( aka providing your opinion ).
> You're calling Krauthammer a war criminal, which is patently false.
It's not patently false. It's a matter of opinion. Lying and advocating for an illegal war which resulted in the deaths of hundreds of thousands of people in my opinion is a war crime. And stop acting like "war crime" is some universal objective term that we can all agree to. It isn't. War crime is just opinion. Was hiroshima or nagasaki a war crime? Some say yes, other say no. So your assertion that it is "patently false" is patently false.
> He may be wrong-headed, but since he never actually acted in the war, never served as an agent of the government
He was a propagandist for the government supporting an illegal war. It's naive to believe he didn't serve as an agent of the government. Maybe the washingtonpost you know is different from the one I know.
If you could provide any legal justification for the invasion of iraq, then maybe I would reconsider my opinion. But you can't because there isn't. So you'll stick to your opinion and I'll stick to mine.
