...................huh? I have no idea if you meant this as a joke but in case you didn't, how in the hell does one person stating a second yet opposite viewpoint somehow delegitimize/erase the first viewpoint?
Cees point was that you said no one had refuted any of your arguments and he showed you a specific example of someone doing just that, just because someone else had an opposing opinion afterwards doesn't automatically cancel out that first opinion as a proper refuting*.
What kind of logic is that?
*BTW, Refute does not just mean to prove something false, it also means "To deny the accuracy or truth of"...in this case...a statement. In other words, to challenge your arguments, and some have.
