This is a philosophical post, intended to spark thinking and examining.

Often, things are talked about like they are a light switch.

Either on, or off.

With each side paired off against the other:

You’re either an introvert or an extrovert.

You should always be assertive, otherwise you will be a pushover.

All boys should act and are like X.  All girls should act and are like Y.

You either have to be a complete shut in, or be a wild exhibitionist.

You must follow this precept, else be cast forever in sin.

You’re either with us, or against us.

It’s all you are/it is X or Y.

Whole worlds of divisions.

Light on.  Or light off.

Here’s the thing about lights, though.

They have things called dimmers.

Gradients are possible (and normal).
