One good reason that the WT demonized the cross was/is the fact that it was a pagan symbol LONG before it was theirs. Just like pretty much everything else. You can find crosses from many many cultures in Old Testament times, and it can be found even in pre-Biblical cultures. I'm sure the Romans weren't using that formation as a means of execution out of any respect for religious symbology, but out of expediency or efficiency in putting these people to death in this very public humiliating way.
The Bible sayes to tear down the "Asherah Pole" mentioned 14 times. Making the pole or stake which the Insight on the Scriptures Vol 2 page 1116 says, "In classical Greek the word (stau ros') rendered "torture stake" in the New World Translation primarily denotes an upright stake, or pole, and there is no evidence that the writers of the Christian Greek Scriptures used it to designate a stake with a crossbeam." So with your logic than the stake is equally a pagan symbol and should not be used either.

If the stake is so correct and the cross is so wrong, why does the WTS have to misinterpet those that say that Jesus died on a cross? Why can they not find enough support for the stake and just present that information?
Also when Jesus selected the WTS as the only true relegion, they taught that Jesus was crucified on a cross and Rutherford had the following to say in The Harp of God:
"And Pilate, more righteous than the clerics, posted over his cross the sign: 'Jesus of Nazareth, the King of the Jews.'" (page 136)
"When Jesus died upon the cross of
"The ransom price was provided at the cross. The cross of Christ is the great pivotal truth of the divine arrangement, from which radiates the hopes of men." (page 142)
"In the cross of Christ I glory,
Tow'ring o'er the wrecks of time;
All the light of sacred story
