I think this is insightful, even though I do believe in the true divinity of Christ (i.e. not a Unitarian). In my experience, a fair evaluation of the biblical evidence is hindered by the fact that the trinity isn't allowed to be false. The trinity is believed to be true independent of what the Bible has to say about it, so people find a way to make scripture fit with the view.
Trinitarians of course will object that their view rises from scripture, rather than being imposed upon it, which isn't an entirely unfair assessment. It's the best theological system of the godhead that's presented itself in history, at least in the mainstream. But in our day at least, that respectability has transitioned into presumed inerrancy, such that it can no longer be held accountable to the words of scripture.

Major reasons people are Trinitarians:
1. They think there is a strong scriptural case for it.
2. People they grant authority to (pastors, theologians) tell them it's true.
3. They believe there will be major social repercussions for them if they question it.
4. They have a strong emotional attachment to the idea that Jesus is God (they think it would hurt Jesus' feelings to say he isn't).
I think the only way for all the scriptural arguments against 1 that you see on X all the time to be successful, is if 2-4 don't hold a lot of weight for a person.
For ex., if they don't really care about authority figures in their denomination - they question them anyways. And if they value truth highly and so don't weight the social consequences of questioning the Trinity as much. And if they don't already have that strong of an emotional attachment to the idea that Jesus is God.
If all 3 of these line up, then the scriptural arguments against the Trinity can strike home, is my guess.
