I tend to see the topic of vocal pitch correction as a logical condition (IF / AND / THEN)
-----------------------

IF some body does NOT use correction... AND they sing on pitch... THEN they shouldn't use pitch correction

IF somebody DOES use pitch correction ... AND they subsequently sing on pitch... THEN they SHOULD use pitch correction

IF somebody DOES use pitch correction... AND they still CAN'T stay on pitch.... THEN they should get off the stage


If you don't use pitch correction and it hurts to hear you sing... at least respect your audience enough not to brag about not using pitch correction, as if that's somehow noble.
