Neither states that this conference removed these books to spite Christians.

Then your articles were incomplete.

I’ve stated before, leave the determination of the Jewish canon to the Jews themselves.
If the Chief Rabbi of Israel - certainly, you must be willing to grant that his knowledge of Jewish law and tradition is superior to any in the Christian world - feels no need to include these books in the Hebrew Bible, why should you?

Even if the Jamnia was violently anti-Christian, valid reasons may have existed for removing these from the Hebrew Bible.
If the leaders of Jamnia wanted to discredit the Christian faith, they would have chosen to remove or rewrite passages from other parts of the Hebrew Bible that more explicitly point to Jesus of Nazareth as Messiah.
If these books are that important to God's revelation to the Jews, why haven't Jews in modern times shown any interest in adding these books to their Bible?
In the end, the actions of the conference makes no difference. None of the books makes a claim of divine inspiration and Jesus never quotes from them.
