*ugh*

I find it irritating to say the least if me pointing out that the entire foundation for your line of argument is 100.0% false... is regarded as not relevant (?!).
Frankly, that's about as relevant as it can possibly get. That's a point that isn't even debatable anymore to any degree as it's just a complete error in plain sight negating your entire argumentation.

Put in other words : if an entire bulding collapses into itself because its foundation was built on sand and made of grossly inadequate materials - you really don't discuss whether the window dressing in that building was appropriate or not.
