You believe that, contrary to he Bible explicitly defining Lord God Almighty as only the Father, that Unitarians are wrong for believing that and that you would have to throw away the Bible to believe the Bible? Sorry, I am trying to be polite but that's ridiculous. I would definitely be a Trinitarian if God was ever defined or described as three persons. If the rest of the Bible was ignored, one may be able to argue a Binity version of God in John 1, but the Trinity version of God is too fractured and debatable.
Unitarianism can't be debunked because it works well with the entire Bible. We pretty much have full reign over the entire Scriptures since God is, without exception, described and identified with singular personal pronouns from cover to cover.
