If I were to sum up the Clerith tactic I see most often, I'd call it Context Avoidance. They look at everything as an isolated incident, instead of asking themselves how it fits in the whole.In short, A is employing- in her assumed role- a debating 'tactic' best called the Wall of Ignorance.
Just take all the quotes from RF: koibito, Cloud and Tifa would be together, Tifa like any woman who's been left by a man, etc. They look at each of these quotes and try to find a loophole (Cloud's name isn't mentioned! They'd be together in the same location!) instead of taking all the parts and examining how it all fits together.
