I'll skip all the parts where you don't understand my point, or where you're just saying nonsense, and jump right to the heart of the thing (other than "you don't get it"):

So, in other words, when you say "instantly", you mean "not instantly".

That's a pretty great metaphor for your entire line of argumentation.

I would respond to the rest - there's a million things there that I'd love to dissect, e.g the admission that you haven't even tried the thing you're so against - but why would I bother? When you say things, you mean things that aren't the thing you said. Case closed.
