I strongly disagree.

When someone is wrong, you can correct them. When someone is lying, i.e. knowingly spreading falsehood in an effort to manipulate an audience, it's vitally important to call them out on it. People need to recognize who is using misinformation as a weapon. The points of highlighted are manipulative rhetorical techniques, not merely bad arguments. These people need to be identified and shunned, especially in a place as committed to dialogue as HN.

Sorry you don't like my phrasing. What method would you suggest to call alarm to a dishonest actor in a public space?
