So respect for other cultures is good, blackface seems, and to me always has seemed, really stupid but I think an apology, an acknowledgment of error, should suffice for us to then move on. And I don't know what should be done about Carmen, but I really like the music.
Context and history matters. While gypsies may have been discriminated against in parts of Europe, there hasn't been much of that in the US (most probably wouldn't even know what you meant by "Roma culture"), so dressing as a gypsy for Halloween doesn't suggest any kind of disrespect.
But blackface was historically used as a way to lampoon black people. It was part of minstrel shows, which were full of derogatory stereotypes about African-Americans (and the blackface they wore was cartoonish, another way of ridiculing the subjects). While someone wearing blackface in modern times would not actually be putting on such a show, the mere act of calling back to those practices is felt to be disrespectful, much like monuments to Confederate leaders in the Civil War.
It's also kind of like why there's almost no context in which a white person can use the N-word without getting into trouble.
