Stop unnessasary censorship

I have a simple question. Is "jewbacca" an offensive term that should be banned from a skit.

to give some context. For the low brass skit my section was going to have jewbacca, me, be an instructor. When someone would mess up I'd tackle them offstage and we'd continue, then I would take a few more people and then give birth to baby jewbacca(fyi, I'm a dude) and he'd finish off everyone left. Would calling me jewbacca be offensive? I think not, but the staff said no, and I protested unnessesary censorship. And btw, I am blood jewish.
