Unity

Common threat unite us.  What do I mean?  A Yorba man can fight a fellow Yorba man but if they are attacked by a fulani, they fight the common threat together.
If a Yorba man and a Fulani meets in a foreign land and are attacked by Indian or Chinese, even a Caucasian, they unite to find the enemy.
And also if the earth is invaded by aliens, that is when,  across all race,  we speak one language. Colour,  Creed and religion matters not as we fight the common threat.
Then let's ask ourselves,  should we wait till a common threat before we are United? No,  we should always be one. I love you,  whether you are black or white.
