You are entitled to your opinion. If more people thought that way we could all be protestants. It would make life easier.
Are prepared to say that belief in Christ's divinity, his sacrafice, death, and resurection are NOT the central core beliefs of Christianity?
Nothing else matters WITHOUT that first, so, RELATIVE to that, everything else is less important.
That does not make me a Protestant.
Catholics and Protestants are both Christians first.
