Polycarp, Iraneus, Ignatius, etc have all attested for the authenticity.
I wish you'd link us to not only the authors, but also the writings that you claim as evidence. It's really not helpful of your argument to present nothing but endless pages of off-putting text through which one must search to find the minuscule parts that you have misrepresented/misinterpreted as supportive of your view.
Also, no one said John was the only human alive with those view points about Jesus, so I don't see how pointing out the others changes whether or not John's Gospel is a misrepresentation of what happened or not.
The point, after all, being presented here is that there was a small group of people who believed Jesus was God (one of whom was John), and so John (and likely others of this group) instead of trying to honestly depict what might have happened in Jesus' life tried to change history (or just write his own) in order to push his particular view points.
You are constantly alluding that grand conspiracy pervades most of Christendom as a way to malign the gospel. You're welcome to do that, but don't be surprised when somebody points out that this is what you're doing.
Stop it. Unless jar says this, you need to quit putting words in peoples' mouths. And it is all irrelevant, anyway, because the issue being discussed is John and the authenticity of it, and moreso
why it came to be written and lead to Jesus being deified.
All of the biblical and extrabibilical evidence suggests authenticity, whereas your "evidence" is basically tongue-in-cheek.
You're acting like a fool. Just because other people agreed with John doesn't mean what he wrote was accurate in any way. It doesn't make his account right.
Much like John, you are putting words into peoples' mouths that they never say.
