The four emcees are caricatures of popular celebrities of the day, men who typically hosted revues (e.g. Bing Crosby and Maurice Chevalier). Ironically, it’s the song “Let’s All Sing...” that highlights this.
Also, since when do ethnic accents immediately equal racism? Especially when there are no jokes directed against any of those cultures? The accents aren’t played for laughs, either. It’s definitely a clumsy 1960s attempt to sound a bit more exotic in Adventureland, but none of it is racist.
And “misogynistic”? Because of the showgirls that are still common in revues? Please quote the actual lines that are hateful towards women.
I wasn’t going to reply because I don’t want to start a wildfire that requires an administrator, but the Internet has made it too easy — and popular — to carelessly toss around hypersensitive labels that don’t actually apply.
