I believe I used to drive by an Elizabeth Ann Seton Roman Catholic Church near Ocala, Florida. My own Catholic dad, grandparents, and aunts & uncles used to regularly refer to themselves as Roman Catholics. They were from Toronto.
Roman Catholic or Latin Rite Catholic is only one of the rites of the Catholic Church (those under the See of Rome). So Catholic is more correct but Roman Catholic does not bother me, but it does leave out quite a few Catholics.
