My goal/point was trying to demonstrate how patently wrong the earlier statements were. The evidence or examples you provide should make that clear. Unless you have very strong irrefutable evidence, I would hesitate making any absolute statement declaring someone wrong. What does it gain you? No one likes to be told outright they're wrong. The goal shouldn't be to score points: it should be to reach common understanding. If this is something you'd like to cultivate further, you might find the references in my profile useful. I refer to them myself regularly.
