By taking a position/hypothesis and extending it to an allegedly logical conclusion, they attempt to generate an internal inconsistency thereby invalidating the original hypothesis. What we're dealing with here is better described as a false syllogism, since there's no reason the FL rule set should be either 8-man premades and GC stacking or feature a complete ban on all methods of communication.
Only the OP can clarify. I don't like pretending I know the thoughts and motivations of others, unlike the psychic members on these boards.
