Well, when someone singles out seed oils, they almost always are saying that butter is somehow better which is why I ask. And from there I ask them for the evidence so I can gauge their epistemic standards.

For example, your comments make no effort to distinguish saturated fat from unsaturated fat. Unsaturated fats are fine. Saturated fats have a mountain of evidence converging on their negative health impact.

That's just what Big Fat wants you to think.
