And why can't I enjoy a steak unless its cooked at the very least to medium?
Because that's the way you like it. That's why there are so many different ways to cook the same food. That's why eggs aren't just fried hard, boiled hard, or scrambled hard. When there is a perfect answer to that question, I'm afraid, we'll all be born in science labs, eating test tube food, and living in Woody Allen futuristic movies.
Fortunately here, while everyone is out for the same pleasures, we share our opinions, and allow free flowing of ideas without making those of differing opinions feel like idiots. At least that's how I have been treated.
