We often see "starting from a false premise" enacted on here. Believers will start from the basis that there is a god.
Bible believers will start from the basis that it is the word of god in some measure, and worse are JW Apologists, they pre-suppose that the first two are a given, and that their beloved Property Company posing as a Religion is god's organization.
None of those premises have been proven, some have been disproven, but we are supposed to go along with them.
Now, you may be happy to debate on that basis, in fact it is probably good "exercise", but in the end I find their arrogant, unproven assertions begin to really annoy me, and then I stick in what is known on here as a "Cofty", which is a short, succinct comment that points out the big hole in their presentation.
The only thing you find then is, either the Apologist cuts and runs, or totally ignores your "Cofty".
I think, even if we enjoy debating for a while with such people, at a certain point we need to call them out on their False Premise, or premises, otherwise a J.W lurking here may simply accept the words of the Apologist and gain nothing in the way of truth.
