Two things.
This section I've quoted where you claim ignorance is ignorant at best, and a complete lie at worst. Every single member of UA, myself included, who went into that Discord saw you specifically make inflammatory comments directed at Prometheus. While you may not have been as "bad" as the others in terms of what you said, you were most definitely involved, and you most definitely took part.
On a separate note, prior to this incident, you were given multiple 'final chances' to correct your behavior and cease being a nuisance. I have serious doubts that this is the real new leaf you're turning over. You consistently promise to be better, and then get banned again only days later.
If I were the only person that had to put up with you, I would have an easier time reconsidering your ban. However, we have 30+ staff members who give their freetime to the server, and I don't really think I should punish any of them by making them deal with you... again...
