I would if "Chang" was the name of a dumb older brother in a mob movie. Try as you might, you'll never make "Fredo" as bad as wop, dago or the n- word, so stop while you're way behind.
No one said Fredo was as bad as other ethnic slurs, only that it was one. It is a derogatory term for a dumb Italian, which is an ethnic slur. Would you call a Black guy, Uncle Tom? Yeah, you probably would. Do you order your Chinese food in a mock Chinese accent? Hop Sing send flied lice, lickity split!
Only Italians care if you call them Fredo. I couldn't care less what you do. Fill your boots. I'm only stating the fact that some Italians consider Fredo to be an ethnic slur. Don't they have the final word?
