The point of a straw man argument is to present a phony (and easier to refute) picture of an opposing argument. This fake copy of the opposing argument is then refuted, creating the illusion that the actual opposing argument has been refuted.
The WT$ frequently resorts to straw man tactics when arguing against the Trinity doctrine. A couple examples:
If he is one Jehovah, then could he be three gods, God the Father, God the Son and God the Holy Ghost, as the Trinitarians teach? --WT, 4/1/1970,p.210.
This is a misrepresentation of the Trinity doctrine, which actually teaches "Jehovah" is ONE God, not "three gods". By misrepresenting the Trinity as being "three gods", the WT$ can then point to verses that teach there is only one God, and create the illusion that they have debunked the Trinity doctrine.
At Zechariah 11:12,13 (AS) Jehovah speaks of "thirty pieces of silver" as "the goodly price that I [Jehovah] was prized at by them." At Matthew 27:9,10 the prophecy is applied to the price Judas received for betraying Jesus. Does this indicate thatJehovah and Jesus are the same person, as taught by trinitarians? --WT, 4/1/1959,p.224.
Again, a misrepresentation of the actual doctrine. The Trinity doctrine does not hold "Jehovah" and Jesus to be the same person. After erecting their straw man, the WT$ will point to verses that contradict their straw man trinity doctrine, thereby creating the illusion that they've refuted the actual doctrine.
