Talk of aliens in the pb reminded me of the preacher clip from TV show Bablyon 5 (Babylon 5 - S03E20 - Preacher Clip) in the context of what Q has mentioned in the past.

Every day, here and at home, we are warned about the enemy.

But who is the enemy? Is it the alien? Well, we are all alien to one another.

Is it the one who believes differently than we do? No.

Oh, no, my friends.

The enemy is fear.

The enemy is ignorance.

The enemy is the one who tells you that you must hate that which is different.

Because in the end, that hate will turn on you and that same hate will destroy you.
