Because if there is in fact another side then the "other" side must of necessity be the INHUMAN side.
Now how can millions of humans be inhuman? Isn't that a contradiction in terms?
Like Schroedinger's cat...is and isn't and you don't which until you peek. Because all you have is possibility until you check out the reality
The question then would be were the inhumans placed here to destroy we the people?
Were they defects of birth? That's doubtful but I suppose possible.
How did they get here and what was their prime directive and who gave it?
So many possibilities. We can never know can we?
