You are obsessed with denominations so that you can call them 'cults.'
Baptists believe the Bible which indicates that baptism is for those who profess repentance and faith in Christ for salvation.
Baptists also believe that each church is independent, so the question of denominations should not apply.
Pseudohistory
The First Baptist was an Anglican. John Smyth. And the kicker is he later left it BECAUSE HE ADMITS NO SUCCESSION, He KNEW he had zero lineage to Jesus. If for a minute he believe the "independent" joke. He wouldn't have been bothered by it all.
Who baptized him? John Smyth wiki:
====
"Since there was no other minister to administer baptism, Smyth baptized himself"
Before his death, Smyth regretted the fact that he baptized himself, and wrote a letter of apology.[6] Due to some shared views, including the Christology, he began a rapprochement with the Mennonite church .[7] This resulted in his excommunication from the church by Thomas Helwys. Smyth and part of the church joined a Mennonite church, while Helwys and another part of the church returned to England to found the first permanent Baptist church in 1611.[8]

Not even Jesus baptized himself.
Reformed Baptist, John Bunyan Anglican roots again.
There are ZERO baptist prior to these guys.
You got your Mennos, they dont' believe in OSAS.
You got your Anabaptist they don't believe in Faith Alone.
The point is Baptism.
We Catholics recognize Baptism even to the point a NON-CHRISTIAN can baptize you.
If you were already baptized and then decided to be Catholic, you would not be baptized again, your already son/daughter of God.
Whereas if you have to point back to lets say Anglicans where your first pastors come from and they say well all their beliefs and baptisms are false, grab their scripture and start over, Who baptized the first? Where do you even start when you have nothing.
