Munchies:
You are a troll. There's nothing to understand.
Some people choose not to feed the trolls. Some choose to point them and make them dance.
FatGTP:
Your craving for attention is your motivation, not any moral considerations. You simply enjoy playing the superior one and don’t even notice how much you yourself are becoming what you hate. Outsiders rarely bother to analyze threads completely. They only see two people squabbling. You probably haven't noticed that yet.
That implies you've ignored what people other than Munchies, have said in this thread.
Plus, Munchies has already told you she is a sadist who will troll back the trolls. You don’t need to assume her motivations, she already asserted that, and her behavior aligns with it.
At this point, for me, this is litteraly just an exercise to point out the logical fallacies and inconsistencies you make.
