These are a lot of accusations. Do you have documentation? Also, just glancing through, are they all completely unreasonable? Just an example:
- Jews also have a law that they can’t marry outside their religion, so what’s the big deal?
- Sex outside of marriage goes against both our moral codes, so again, what’s the big deal?
- I have worked with many Jews - they don’t eat with us, or hang around while we’re eating, because Gentile eating habits make them feel physically ill. Perhaps the third precept was for the comfort of the Jews, and not to ostracize them?

Secondly, with regard to documentation, do you have anything to support this accusation?
I have read the documents of
both Councils of Nicea (the first was in 325 AD and the second was in 787 AD);
neither Council made any mention of the Jews in any context whatsoever. The subject of the First Council of Nicea was the Divinity of Christ - it produced the Nicene Creed. The subject of the Second Council of Nicea was the proper place of images in worship.
