Did you just arrive on earth from another planet?????????????????????????????????????????????????????
All the other "Catholic sects" do not recognize the pope as supreme pontiff and thus are not part of the roman Catholic Church.
do a google search pogo and surprise yourself with the myriads of references to the Roman Catholic Church.
YOU are being petulantly obstinate and contentious. shame on you!
You are the one who is being stubborn and obstinate.
In the Catholic Church there are different liturgical Rites, 24 in total.
ALL Rites adhere to the same doctrines and ALL Rites are in full communion with the Pope.
There is ONE Church - the Catholic Church with what are known as particular churches (not sects).
The Catechism which we quote from is the
Catechism of The Catholic Church -
not Roman Catholic Church
They differ in liturgical practices and some aspects of governance.
There is a useful article in Wikipedia explaining this with a list of the different particular churches.

A couple of quotes:
There are 24 autonomous churches: one Latin Church and twenty-three Eastern Catholic Churches, a distinction by now more historical than geographical. The term sui iuris means, literally, "of its own law", or self-governing. Although all of the particular churches espouse the same beliefs and faith, their distinction lies in their varied expression of that faith through their traditions, disciplines, and canon law. All are in communion with the Holy See.
The word "church" is applied to the Catholic Church as a whole, which is seen as a single church: the multitude of peoples and cultures within the church, and the great diversity of gifts, offices, conditions and ways of life of its members, are not opposed to the church's unity. In this sense of "church", the list of churches in the Catholic Church has only one member, the Catholic Church itself (comprising Roman and Eastern Churches).
Yes you will see the term
Roman Catholic applied to the Latin or Roman rite. My own diocese is the Roman Catholic Diocese of Liverpool because it serves Roman Rite Catholics in the Liverpool area.
And yes, you will see a lot of local churches caller
Roman Catholic Church because the Latin or Roman rite exists mainly in the west.
But to refer to the Church as a whole as the Roman Catholic Church is incorrect.
