They lost me at this point: "Butter tastes much better than margarine and it can enhance the flavors of other foods."

This is an opinion, not a fact. I prefer the taste of margarine. And nothing can ruin the taste of home-made sloe jam like butter - not even stale bread.

And since I had to experience cowsheds, the home-slaughtering of a pig and the butchering of some chickens at my grandpa's, I prefer food that was processed in food-factories, thank you very much.
