I guess you are entitled to your interpretation. But every point you have been making has another interpretation that doesn't impune his reputation, much less turn him into an antichrist. Nearly all of the great Bible scholars for nearly 2000 years have looked at the same text and not viewed it that way.
I don't ever take things personally. But I'm certainly gonna defend my man Paul. As far as I'm concerned, he was the greatest and most influential of the Apostles. I've been teaching advanced adult Bible classes for the past 13 years. I have many hundreds of hours in the classroom and spent thousands of hours comparing his teachings with all other Scriptures on every topic imaginable. His teaching hang together with the rest of the Bible perfectly - and in fact no one has ever done a better job of unifying all of the Scriptures than Paul.
As I said above - none of the Apostles objected to Paul or he would not have gained acceptance in the early church. John outlived him in Ephesus by a generation and had plenty of time to stomp out any of his alleged false teachings. Many of the first century church fathers quoted him. Peter did indeed refer to Paul's letters as Scripture, in the verse we have both quoted multiple times. To paraphase, "Our brother Paul's letters are hard to understand and people twist what he says like they do all the other Scriptures."
Peter is commenting about Paul's letters which comprise 49% of the New Testament. He is not talking about Paul himself.
