Your interpretation of some Old Testament laws: "Most of what you mentioned were laws, established by men, belonging to the Nation of Israel. They were not laws established by God. They were laws established by God's chosen people."
I assume you did not read them in Aramaic. You read them in English. They are quite clear. Let's take Leviticus 19. It starts with:
"And the Lord spoke to Moses, saying:"
That is God talking, not some men.
Continuing:
"You shall keep my statutes. You shall not let your cattle breed with a different kind. You shall not sow your field with two kinds of seed, nor shall you wear a garment of cloth made of two kinds of material."
So again, that is God saying "obey my laws." But you reinterpret them in a way that you do not have to obey them, because they are inconvenient to you. You have, in other words, inserted your own meaning into a Biblical law that you do not want to obey,
This isn't some horrible sin. It's what you have to do to take the Bible seriously at all. But it does get a little old when you attack others for doing what you yourself do.
