The Foreign Key

I have only an extremely marginal understanding of relational databases. I remember being introduced to the concept of a foreign key, which basically controls all the values that reference it.

I understand foreign keys like this: If humans are the most intelligent species on the planet, then X, Y, Z.

What if elephants are smarter? The whole string falls apart. (Again, I may be butchering the true definition, but stay with me.)

So. White privilege is kind of a foreign key. I think the reason so many white people have denied white privilege is because they are afraid of what that would mean if their whole worldview has been with or without their knowledge predicated on an invalid foreign key.

What if rap music is no more dangerous than blasting Brahms?

What if a resting expression is just a resting expression, no matter what color the face?

What if tall is just a genetic trait and doesn't have a inherent relation to aggression?

What if people are only dangerous or stupid because they really are dangerous or stupid?

What if there is no way to tell from looking at a person if he or she is friend or foe? What if you couldn't be scared by a hoodie?

What if we've been fooled by selective history?

What if the foreign key is invalid?

The whole system collapses. And only then can we rewrite the logic to represent all possibilities, and not just the prevalent one.

Question everything.
