One can stand their ground and not stoop to the level of grotesque mud-slinging this is turning into. Let's say Royse777 lied, PP can add this statement to the OP and not add more negative ratings. I don't expect de-escalation any time soon but I think by now it's quite clear where the sides stand in this debacle and I doubt anyone's opinion will be significantly affected if one of them stops counterpunching.
Your apparently right. The good gesture to any peaceful coexistence is understanding each others differences and be willing/ready to make necessary adjustments. Being right in a contest of words with nothing else to hedge on could be such a difficult thing to archive when it's put in contest. Its always going going to have a direction to turn with any capped pinnacle and so, I'll suggest they both be wrong in there perception of long ago and current claims to move on. That feels like the more easier thing to do.
I don't xoect my word to mean much here, like Suchmoon has stated, opinions don't significantly matter with all sides believing to have something to prove so, let the parties be wrong to be peaceful than be right and throw punches.
