Of course it is. Your self-described propaganda is laughable.
Many deny there is even a thing called the Roman Catholic Church.. that the roman church IS THE church(that all other(churchs) are NOT.. You must be/could be.. one of "those"..
What is laughable are those that think there is no difference between "the church" and "A church".. and try (by propaganda) to hide(occlude) the issue.. You know.. to hide the issue from lurkers.. or some that could care less either way.. The roman catholic church is a denomination as any eastern orthodox(various types) will testify.. However the eastern orthodoxy(s) are denominations also..
I have no problem with the RCC being a denomination.. but the roman denomination is not the universal church, or body of christ.. or the bride of christ.. merely a sheep pen as any other denomination(John ch 10).. Limiting the body of christ to any denomination IS HERESY... and part of the spirit of anti-christ..
