I've been thinking about how to answer this question ever since I saw it yesterday. I suspect I will come back and edit this answer as I continue to ponder it.
(1) I'm kind of working my way down Kurt Harris's Archevore list, so when I think of my "paleo journey" (PIMMAL at that phrase, but I hope you know what I mean here), it isn't simply a way of eating but a combination of better sleep hygiene/different exercise program (more weight training and sprints, less cardio)/food choices/minimalist footwear most of the time, with food being only one component.
(2) I actually operate on the principle that other people's interest in what I do to maintain my health is really pretty superficial, and my particular food choices on any given day don't even make it on other people's radar. For example, who's gonna really notice that I order sashimi rather than sushi when we're out at dinner, or understand the significance?
(3) When you add 1 + 2 together, it means that any discussion of "paleo" that I would have would be MUCH longer than anyone would want to listen to, unless I was comparing notes with another paleo person.
The subject on which I am most likely to engage "civilians" in discussion is sleep, but this is much less emotionally loaded than the subject of food, and I feel confident about my knowledge and its limits in this area. I'll discuss exercise only when people will stop me and ask me what sports I do (I swear this happened yesterday, and I'm 53 years old!). I'm far less of an expert about exercise than about sleep, though. I am willing to talk about the process of making fermented foods because it is an interesting hobby to some. But if someone offers me a piece of birthday cake? I will refuse it without explanation.
What I'm groping to express here is my notion that mutuality, or perhaps it's reciprocity, should apply in matters of food. I don't want people pushing food, or diets, on me that I don't want. I therefore should apply the Golden Rule and not push food, or diets, on other people that I can't be certain that they want. I once had a client who gave me a copy of The Zone Diet as a gift, and I was mortally offended. I was somewhat overweight at the time. I would rather she have made a payment on her account, which was in arrears.
I've also seen the pendulum swing on various issues too often over the years to believe that I have the final answer on ANYTHING nutrition-related. I was a Dean Ornish gal in the early 2000's, and at the time I thought I was acting in my own best interest. I can only act on the best knowledge I have today.
