Ten Commandments is common sense that the tide-pod eating, condom-snorting millennials need to be taught. Most of the kids these days just don't know basic things, like where many countries are on a map etc.
Modern-day Paraphrase of the Ten Commandments:
Do not worship any other god than the one true God. All other gods are false gods. Worship God alone. (this is where we live, the air we breathe everything and all)
Do not make idols or images in the form of God. An idol can be anything (or anyone) you worship by making it more important than God. If something (or someone) has your time, attention and affections, it has your worship. It could be an idol in your life. Don't let anything take the place of God in your life. (hmmm, sound familiar? American Idol, Facebook etc.)
Do not treat God's name lightly or with disrespect. Because of God's importance, his name is always to be spoken of reverently and with honor. Always honor God with your words.
Dedicate or set aside a regular day each week for rest and worship of the Lord.
Give honor to your father and mother by treating them with respect and obedience.
Do not deliberately kill a fellow human being. Don't hate people or hurt them with words and actions.
Do not have sexual relations with anyone other than your spouse. God forbids sex outside of the bounds of marriage. Respect your body and other people's bodies.
Do not steal or take anything that doesn't belong to you, unless you have been given permission to do so.
Do not tell a lie about someone or bring a false accusation against another person. Always tell the truth.
Do not desire anything or anyone that does not belong to you.
Comparing yourself to others and longing to have what they have can lead to jealousy, envy, and other sins. Be content by focusing on the blessings God has given you and not what he has not given you. Be thankful for what God has given you.
Maybe the ten commandments should be displayed in public schools and taught throughout the nation because it is very moral and to say the least it can be very helpful in understanding about history and what some people believe to be written by God himself and is really quite interesting.
You should not force people in a public school to be forced on your beliefs in a learning environment. Also the Ten Commandments are not necessary in learning about history and if a child is interested they would investigate it on their own. Also teachers are not supposed to have a bias on what they teach and teaching the Ten Commandments or any other religious form could cause them to teach in a bias way.
Public schools are secular in nature and it should not be a place to spread religion. These institutions are supported by tax money, and not everybody in a given community will be Christian. If a religious person wants their children to see the Ten Commandments every day, they should put their children into a private school.
