I completely agree ... IF IT IS CLEARLY LABELED AS ONLY SPECULATION.
Without a clear and unambiguous disclaimer, capable of being understood by almost ANYONE with a 7th grade education ... so clear that it CANNOT be misunderstood ... it is merely a false prophesy, intended to keeps the troops motivated, afraid, and keep the money rolling in.
I understand you may be concerned about adding anything to scripture (or taking away), since that is a very serious thing, but adding something to what is after all human speculation, surely is not a big deal?
Also, what Jesus Christ is saying to us now, is what he said 2000 years ago, and is recorded in the Bible for anyone to see.
#1 We will not know the "day or the hour" until it occurs, but we have enough evidence to see that we are, as David Shafer said "right on the cusp of the Great Tribulation

This is AMERUKA! We don't use no stinkin' SI Units in AMERUKA!
We are red-blooded Bible-Totin' red white and blue people that use FEET, and INCHES, like the Lord intended normal people to use. Millimeters, PAH!, that what drug dealers use when rolling reefers!
Here in Ameruka SI unites is an abbreviation for SISSY man ... the kind of man that will watch Star Trek and yell for Captain Kirk to set his Phaser on STUN!
REAL MEN don't use STUN. and REAL MEN don't use millimeters !
