laughing their asses off at the irony that the subject can't protest without admitting he's a deranged nutter for imagining such behaviour?

mav, they may be "laughing their asses off", but they merely demonstrate that they lack sufficicent confidence in their argument to subject it to open debate. Howevermuch they enjoy thinking themselves clever, they in fact show the reader that they have nothing better to offer than rhetoric and adjectives. Hence their "subject" need not trouble to refute; res ipsa loquitur.
