Oh, okay, I'm sorry I got something from the tone of your posts that you say isn't there. I honestly don't even think about "feigning" anything. This is just a friendly chat, then. But I disagree with you to the extent that in my specific example, so many people bought into the advice about what was good and what was bad, it became pervasive enough that a great many people did indeed consider it common sense. These kinds of things become ingrained in our culture and are difficult to root out, even when proven wrong.
As an aside, I find it almost surreal that I am being called to account for wanting changes to school lunch programs to actually produce meaningful results. Why would this be a controversial stance, other than it's perceived to be hostile to a certain ideology? Like lots of other things, our kids health ought to be above partisan bullshit, but hell, no, it poisons every discussion.
