I was going to actually specify the majors here, but decided that this would also work, not single anyone out, and perhaps even be funny it it's own way.
Purple: MrBeige, you should go back to drawing comics about your
office, not academics in general.
Purple: It would still be funny, and you wouldn't offend anyone with
your critiques.
Beige: I'm not a major, I'm a major.
MrBeige: I don't care about money or fame, I just want to make the
world a bettert place.
