Seroiusly, TTWSYF?
How about a specific example, after all, I should be able to drive a car through your examples, right?
Did you just land on this planet? Go back a few pages and you'll drown in the scriptural examples.
Trinitarians can see the Trinity in a shopping list. It's quickly becoming clear why the Trinity is such a popular doctrine: It's a "faith" doctrine that has been adopted as a rite of passage by "true Christians". The Emperor's New Clothes of dogma, wherein belief indicates faith and revelation of Holy Spirit. If you don't see it, you're a "false Christian", "damned", or you "don't get it". It's not that Trinitarians can't see the Bible rejects the Trinity; they refuse to see the Bible rejects the Trinity, because that will take away (what they perceive is) everything they've worked so hard to achieve in their quest for salvation.
Just like JWs do mental backflips to convince themselves that the magisterium of the Governing Body is in line with Scripture, Trinitarians do the same to justify the Trinity. JWs are convinced you can't be saved unless you have faith in the "fds" (I put it in quotes, because there's no evidence the faithful and discreet slave of Matthew is anything akin to what JWs believe it is or that the Governing Body of the Watchtower Bible and Tract Society is what Jesus described), just like Trinitarians are convinced you must have faith in the Trinity to be saved.
It's the same attitude as the Inquisitions without the laws to allow coercion. People with strong beliefs in weak arguments get very upset when they're around people who don't buy into their beliefs. This is why cults use emotional tactics, separatism, and elitism to oust dissenters and Trinitarians use fear: Imprisonment, torture, death, threats of Hellfire. Their (speaking of all religions with fantasy doctrines) "proof" only exists in their own eyes, because of what they've been brainwashed to see, when they read "proof texts". They cherry-pick Bible translations that support their pet belief and call others "biased", cherry-pick verses, cherry-pick words within verses, and blatantly extrapolate beliefs which aren't there in most cases.
Trinitarians can't be reasoned with, because the Trinity belief isn't a rational one, but an emotional one. Arguing this doctrine is like arguing with someone who insists blue is the best color. Nobody is ever going to convince someone a belief they strongly choose to hold is false or even unprovable. In their minds, it's a slam-dunk and you just don't see it, because you aren't as enlightened. The strongest type of brainwashing is the kind one does to one's self and this is what Trinitarians and other cults do.
