"Classic" Disney also included Davy Crockett, 20,000 Leagues Under the Sea, Old Yeller, Treasure Island, The Love Bug, Swiss Family Robinson, Johnny Tremain, The Sh@ggy Dog, The Absent-Minded Professor and other stories with male leads and/or mostly male casts.
As much as I love those three movies, whittling down ALL of classic Disney to JUST Snow White, Cinderella and Sleeping Beauty, for whatever reason (political, convenience, ignorance etc), is a major pet peeve of mine and many self-identified Disney fans are as guilty of this as anyone else.
