It's only about you because you made it about you.
"Ghoul" is not a slur. You saying that seeing an unpleasant word next to a word that reminds you of anime is at all equivalent to a slur is frankly ghastly of you.
You'd almost have a leg to stand on if they changed it to "Captain Weeaboo" or something, but even then the comparison is a stretch. You're showing up at somebody's funeral to say "I scraped my knee, that's bad too! We're all equal as humans, so I deserve to speak".
Grow up.
You really can't see the forest for the trees. Reflect.
