Bro, if it has no relevance why are you still dragging it around? She came out swinging, are you going to deny that? At the point she came out swinging there were a ton of people who were around who still remembered the shit you used to vent on here. She did nothign but aggravate the situation.
What you're trying to do now is analagous to taking a bag of chicken feathers, throwing it out of a helicopter and then going a week later and trying to pick them all up.
While I dont think I've had any sort of negative personal communication with her, I can say that if she really tried to come back with a clean slate after admitting all the shit she did then it's even more foolish for you to try to defend it, regardless of who she is.
You spoke yourself about faceless alters, isnt that what she tried to do? Come back as someone completely different with a clean slate?
