As we know they trot out the usual 1914/1918/Kingdom/Jehovah bunkum which can't withstand much scrutiny or questioning at all.
We on the other hand have tons of information to disprove their arrogant claims.
Just one small example: "If CTR died in 1916, how come he did not know that Jesus started ruling in 1914?"
And most inconveniently there is JWfacts.com, and Ray Franz' books, parts of which can be read in the WBTS publications.
