The “thing” with cholesterol is that the science wasn’t actually wrong! Eating foods laced with cholesterol is indeed unhealthy, as the data showed, which is why everyone incorrectly assumed cholesterol was to blame, until it turned out that the real culprit was saturated fat, which is concentrated in animal products, which also lots of contain cholesterol.

But hey, all those pesky scientific details would require knowing biochemistry and that is just way too inconvenient for the troglodytes who treat food as a religion and are currently downvoting this comment.
