So is the Old Testament null and void now? Is it completely ignored by Christians?

I don't think there is an answer to your question that you will find satisfactory.

Leviticus 19:19 is essentially telling us that we must not sow good and bad things (seed) into our lives (fields), and that we should clothe ourselves in garments of light/goodness and not in garments of darkness, we must not mix the two. We must not mix the truth with lies in other words, we must only do good things and not bad things, etc.

The Old Testament is not abolished, it actually still stands. But we must interpret the the Scriptures in a spiritual and prophetic sense. The Torah is mostly one big grand metaphor all pointing the way to the Messiah. The Law is deeply spiritual and prophetic.

"Why aren't raped women marrying their rapists? (Deuteronomy 22:28)" While I agree this is quite harsh, there is a very important spiritual principle to be learned. God was telling us that unbelievers (the unbetrothed young virgin) who are mislead (whether by force or not) by Satan (the rapist) will suffer the consequences of being "married" to him, which will ultimately be a life devoted to the Satan's desires which has a nasty consequence of spiritual death. However, in the Torah the father did have the power to annul the marriage, in this case if the daughter requests not to be married the father can annul it, especially since it was done by force. In other words it's up the Yahweh (Father God) to determine the fate of a person

"Why aren't we hiding our feces? (Deuteronomy 23:12-14)" Uhhh, we do actually, its called flushing it away. God knew our feces are harmful if not done away with, so He instructed the Israelites to get rid of feces, especially outside the camp away from people. God is actually really smart!

I can't really be bothered to answer them all.

You have put a lot of thought into this. Of course, not all Christians eat pork-Seventh Day Adventist, for one.

For anything, you have to look at it in the time period it was written. For the cleansing after your period, people did not bathe much back then and needed to be educated. So they wrote it down and it somehow got put in the bible.

You should find someone that studies theology to answer your questions.

While the New Testament was being created, people realized that the figure and messages of Jesus were more humane and the stories of the Old Testament were strict and unreasonable. Christians follow the New Testament because Christ had risen, no longer followed the Old Testament in which Christ has not been considered in the story yet. Some religions--NOT CHRISTIAN---follow only the old Testament.

Your are right. The old law was nailed to the cross with Jesus. See Colossians 2:14

Yeah, they ignore the NT too. Jesus was against divorce and adultery. Jesus told them to gouge out their eyes and cut off their hands if they continue to cause them to sin. Paul told women to shut up and not be leaders of men.

Christians just ignore the bulk of the Book of Ignorance, Bigotry, Lies, and Evil....they have to in order to live in the morality of the world today with our social equality and civil rights and freedoms.

Null and Void - no.

The only text we consider - again no.

The OT is simply part of the Bible, we learn and believe in the entire text. The NT is equally important to Christians.

I can quote Darwin saying the complexity of the eye means there is a God or Dawkins saying there must be a designer. And while both would be complete quotes, as are yours, they would lack the context needed for full understanding.

Practically Christians have abandoned both OT & NT , only Jesus is the Savior works,

You seem to have done your research, which would be good if this was a PhD thesis, but it's not, and I gave up reading half way through.

People still refer to the Old Testament, in spite of what you may have heard. Get over it, or convert, if you really find it that interesting. I can assure you, there are those of us who don't.

Christians are version 2.0
