I'm referring to scenarios where the nonsense is affecting your psychological well being. If you're in a situation where you see nonsense, see a way to refute or diffuse it, and without it causing an emotional response in that moment, then obviously "block and move on" has different consequential implications and isn't a good formula. But the duty to tell the truth only is actionable if you're not plunged into irrationality or weak arguments because of the stress or emotional frustration overwhelming you.
