RDA is based on a 2000 calorie diet, and since the recipe in it’s current proportions has only 1156 calories, it might be easier to interpret if you calculated the total nutrient values by (total % of RDA)*(2000 calories)/(number of calories in recipe), to give sort of a “nutrients per calorie” measure.
Wikipedia says plant iron is harder to absorb than meat iron (“heme” iron), so your percentages for iron may be an underestimate.
Machiavelli wrote in “The Prince” about the similar dilemma of advice. If you let everyone give you advice, you seem like a pushover, but if you don’t take any advice, you’ll probably do something stupid. His recommendation was to have a circle of people who you take advice from, and to ignore everyone else.
A similar system could work well for offense. If you want to be high-status, when most people lower your status, get offended. But for a select few (probably the people who you work with when you’re seeking truth in some form or another) practice never taking offense, as the original post suggests. Ideally, these people would know they could offend you, so they wouldn’t censor potentially helpful ideas.
