Most Americans are comfortable with Cecil B DeMille's version of the Decalogues.
#11: Thou Shalt go see the Movie

2. Observe above all else this Golden Rule: Do unto others as you would have them do unto you.
3. Stay temperate in word and deed.

6. Do not kill the body, or spirit, of another human being.
7. Men, be respectful of women; women, of men.
8. Be free of criminal behavior; in all its forms, it is theft.
9. In matters of behavior, morality, and reputation, be truthful, lest you, in your own eyes, lose honor..

It is an old game, and you will find hundreds of examples with just a short search on line.
But Richard Dawkins picked this one out, so I will go with it, for no other reason that I do not really have time to play.

.Do not do to others what you would not want them to do to you.
• In all things, strive to cause no harm.
• Treat your fellow human beings, your fellow living things, and the world in general with love, honesty, faithfulness and respect.
• Do not overlook evil or shrink from administering justice, but always be ready to forgive wrongdoing freely admitted and honestly regretted.
• Live life with a sense of joy and wonder.
• Always seek to be learning something new.
• Test all things; always check your ideas against the facts, and be ready to discard even a cherished belief if it does not conform to them.
• Never seek to censor or cut yourself off from dissent; always respect the right of others to disagree with you.
• Form independent opinions on the basis of your own reason and experience; do not allow yourself to be led blindly by others.
• Question everything.”

Besides that. You could point out the contradiction that their own prophet Jesus already did it, when he said that there was only one commandment. And that contradicts his own statement that he, came to complete the law, not abolish it.

One shall not subscribe to dogmatic bullshit.

Is this person independently wealthy? The pay disparity would be Staggering!

Thou shalt not exist unless you first obtain written understanding that you are requesting to exist in this existence that no one asked for in the first place.

Here’s a fun exercise you can do with your co-worker if he’s game: Have him write out the 10 C’s as they appear in Exodus 20:2-17. While he’s doing that you write the 10 C’s as they are listed in Exodus 34. (The 1st list is brought down from the mountain by Moses who proceeds to obliterate them upon finding the Israelites engaged in full frontal idolatry with the golden calf. So he gets a replacement set from God who will “write upon these tables the words that were in the first tables, which thou brakest.” Then compare the two lists. They should be the same. (In fact, God says they are the same). But they’re not. They’re actually quite different?!?!?!?!? Ask him to explain that to you! (The most common answer give by scholars to account for this is that one set belonged to the northern kingdom of Israel (which eventually got wiped off the map by the Assyrians) and the other set belonged to the southern kingdom of Judah (Judea). ) I posted about this back on March 20th, with a link to “Why Christians Get the 10 Commandments Wrong” by Valerie Tarico in a Salon article from 2014. In fact, I would just print that article and give it to your friend. It’s pretty damn funny, apart from being very informative.

And there's this:

Thou shalt protect the planet

1. This above all shall ye take as my first command: Thou shalt treat living beings as they want to be treated. And the 2nd commandment is like unto it:

2. In as much as be possible, thou shalt avoid afflicting pain and sorrow, which shall be unto thee my signs of ill and evil.

3. Thou shalt honor and protect all of creation, for I the lord have created it that thy days may be long upon the land which the Lord thy God giveth thee.

4. Thou shalt have sexual relations with neither human nor beast who chooseth not freely what pleasures thou mayest offer.

5. Thou shalt not beat the child, but by admonition and instruction with kindness shall thou teach both wisdom and skill.

6. Thou shalt do unto members of other religions and tribes as thou dost unto thine own.

7. I, the Lord your God, forbid thee to own other persons be they woman, man, or child; neither shall ye subject any gender or race one to another, but shall honor my image in all.

8. Thou shalt not destroy the lands of thine enemies, nor poison their well, nor salt their earth; neither shalt thy cut their shade tree nor burn their vineyard, nor wantonly slaughter the beast of their field.

9. Thou shalt wash thy hands before eating and shalt boil the drinking water that has been defiled by man or beast.

10. Thou shalt ask the questions that can show thee wrong, so that through the toil of many, from generation unto generation, ye may come to discover the great I AM.

Honor thy mother and father is not possible when they are terrible, toxic people.
Too many of us have suffered at the hands of bad parents.

You could not win him over. Looks like you are not going to heaven.

But faith aside, pastors make a much better living than nurses do.

Five or 6 of the commandments have nothing to do with morality. It seems pretty redundant for an omniscient being to toss in his pet peeves with a list of things people should do to be a good person. Now that I think about it, it fits right in with all the bs that is religion. Number 11. Treat others as you wish to be treated.

George Carlin summed up the 10 commandments best. First throw out all the praise and honor god shit, then combine the rest.
