Not surprising that someone will deny that list.
It's what someone who is concerned with truth and facts should do.
The Roman Catholic Church is constituted by those churches which are in communion with the Bishop of Rome: thus Latin Rite Catholics, Byzantine Catholics, Maronite Catholics, Chaldean Catholics, etc.
Sedevacantist churches are not Roman Catholic, they teach that the seat of St. Peter is vacant (that's what sedevacantist means) and are not in communion with Rome; though they do believe they are the "true" Catholic Church.
The Old Catholic Churches are a collection of disparate churches which broke away from Rome over the First Vatican Council in the 19th century, most are united together under the Union of Utrecht.
The Polish National Catholic Church used to be one of the Old Catholic Churches, but is no longer one of them either.
Go ahead and actually look up the churches you listed, here's the first three:
American Catholic Church in the United States, Old Catholic, not Roman Catholic.
American National Catholic Church, founded in 2009 apart from the Roman Catholic Church, not Roman Catholic.
Antiochian Catholic Church in America, an independent Catholic Church founded in 1991, not Roman Catholic.
If it is not in communion with Rome then it's not Roman Catholic. It's that simple really.
