You seem to be presenting a new argument that I haven't seen before, which is interesting, but you're going to have a lot of Scripture to tangle with. For one, we don't believe in philosophical arguments about who God is, therefore we perceive what you're talking about as your god, an idol. We can be engaged with Scripture and you can repeat what Scripture says if you've found where the trinity is mentioned, explained, or described. You would have a case to make and I would listen, but as I said, you would still have a lot of Scripture to tangle with.
The Bible explicitly describes the only true God as the Father repeatedly, like it, hate it, believe it or not, the Bible says what it says. Don't make the mistake of thinking you can make arguments and change what the Bible says like the others have. It will always come back full circle to what the Bible says, which is a higher authority than your opinions.
