It's funny how much we like to categorize things and put it in a neat little box, unfortunately, it just doesn't really work that way. Most things are more complicated than that.
Take diets for instance. There are over a 100 different dietary theories (many piggy-backing off of another) which I studied for my health degree. What I learned from this was that there is not a 1-size-fits all. Kinda like how every girl hoped they could fit into Cinderella's glass slipper and yet, it was made ONLY for her!
I know what your thinking, "what does this have to do with Pie Crust?". Well let me tell you!
