Abusive "argumentation" What marks the aggression of the passive variety is that it is indirect. Like slashing tires, gossip, delaying, pretending to not hear you, backhanded compliments, doing jobs poorly on purpose. It is attempting to hurt you, but behind your back, or without having to take the responsibility for doing so.
The former is worse though, because overt aggression is difficult to gas light from. Hard to deny, whereas one can deny the intentions of causing harm in the case of its passivity, plausibly. Meaning that it is both more difficult to prove, as well as more difficult to disprove, just based in its nature.
I would just highlight that nearly all examples of it are unavailable to me in this context, and so at best, I could be hurling back-handed compliments, or subtle insults, and by nature of the accusation, they would be hidden, and difficult to detect, and thus also difficult to deny, as things that are not obviously insults, could be said to be so...
All I can say, is that passive aggression is difficult in this context, and that I've said absolutely nothing based in aggressive or resentful feelings.
