I wish every time someone established two extreme points, everyone is like you, automatically interpolating an entire space of endless possibilities, countless shades of gray. But this is decidedly NOT how we think, because dichotomies are simpler to mentally process, and in fact ultimatums or "single right solution" situations are easiest to process.

Have you ever seen an online argument? If someone is right, and someone is not AS right as they are, they are a "left shill" and vice versa. If you promote solution A, and someone promotes solution B, then they're "wrong". Not establishing points, just "wrong".

So I think establishing two directions is best accomplished not by marking up two extreme points and leaving the rest to the imagination as our imagination is apparently quite poor.

It's more correct to describe the next step in a direction, and let us take things step by step and know that nuance is inherent to our success, not optional.
