We can only speculate as to the things that are really going on, the evil etc. but then think, nah it can't be really happening, not to that extent.

Imagine those that truly know, have lived it or seen it.

We, that don't truly know can only speculate on such matters, Q provided us a glimpse, a taste of truth. If we truly knew, then it would not be safe for them to walk down the street.

As of now we can only guess and make assumptions so they are safe.
