We are also butter eaters here. I don't believe the "experts" are as expert as they claim. I have a friend who had high cholesterol for years, it was up to 320. She went on the diet, no butter, no red meat, no eggs, and took meds for 25 years. The lowest cholesterol reading she was ever able to get to was 240. Then, she started breaking out in rashes, went to lots of doctors who did nothing to find what the cause was, only prescribed creams for the rash. She finally went to a naturalist (amazing, since she's the very definition of a skeptic), did some testing. She had to stop eating all corn products, flour, soy, sugar, and everything processed. But, she DID start eating red meat, eggs, and clarified butter. Her cholesterol dropped to 200!!!
FYI, while I agree with those who dislike margarine, the "one molecule away from plastic" argument doesn't impress me much - hydrogen peroxide is only one molecule away from water, lol.
