"Words ought not be judged solely on their truthiness independent of their person."

Ok... so who are you? Since I don't know you, I can't judge your statement with any respect to you, so your statement cannot be considered true, so why say it? Truth is quite obviously the sole standard a statement should be judged by. If you give up on the analysis and are looking for a shortcut, then that is something else entirely. Our "ability to discuss" is hampered when your opening statement is self-evidently false circular reasoning.
