I know nothing about the guy except what little I read (past tense) about him on Wikipedia. I just looked over his 12 rules as they are presented there and a couple of things seemed pretty clear.

First, these aren't ACTUALLY 12 rules for life, they're 12 rules for creating a community he's comfortable with. He's trying to build the US into the community he wants it to be. As are we all, right? Not a moral hazard, just something to be aware of going in. Except that by calling it 12 rules of life, he's broken his 8th rule, that is if he is self-aware enough to see what's really going on.

Second, people have a long history of coming up with rules for living that actually shed no light on the basic problem, which is that we - humans - cannot tell right from wrong. The Bible's Ten Commandments are another example of such a list; no doubt there are many others. This problem is the real reason slavery managed to persist for so long, why people can see no problem with invading countries who have done nothing to them, why people allow it to become illegal for homeless people to shelter themselves et cetera. There are many examples of this blindness. Until our rules for living actually include as their primary goal the determination to investigate and develop a way to tell right from wrong reliably, nothing else will really matter very much.

Finally, rules 6 and 7 seem problematic to me. Pursue what is meaningful - this is the kind of advice people give who don't themselves know what is meaningful, and are hoping you will figure it out without them having to admit their ignorance. Set your house in perfect order before you criticize the world - this is a recipe for never criticizing anyone or anything, and never making progress on any problematic issue. Hypocrisy and deception are central to humanity. If we must eliminate them to move forward, we might as well just commit suicide right now. Thankfully, we don't have to do that. We have shown that we can make progress despite widespread hypocrisy and deception.

(I know, I'm SUCH a know-it-all!! Sorry lol)
