Manga logic.
They apologise so much for being excited.
I've never understood apologising for your predecessors. Apologising for someone else only makes sense to me if it's someone you have responsibility for, like a kid.
NGL, I feel apologetic to anyone that has to deal with some of the older generations of my family. I'm sure many can relate as well. Who doesn't have the bigoted/racist family member(s).
Sure it's not really your responsibility to atone for their wrong doing, but you can hardly say their actions doesn't have any effect on your reputation if you don't make a clear statement about the subject. That is what the apology is doing. It's a clear statement that you, at least on the surface, do not follow the same morality.
