Blondie, thanks also for the quotes about the baptism as JW = marked for survival at Armageddon. It also explicitly states the inverse as well:
11 We understand that in the fulfillment of this prophecy, the man “clothed in linen” represents the remnant of spirit-anointed Christians. By means of the preaching and disciple-making work, the anointed class puts a symbolic mark on those who become part of Christ’s “other sheep.” (John 10:16) What is the mark? It is the evidence, as if displayed on their uncovered foreheads, that such sheep are dedicated, baptized disciples of Jesus Christ and that they have put on the Christlike new personality. (Eph. 4:20-24) These sheeplike ones become one flock with anointed Christians and assist them in their vital work of marking still others.—Rev. 22:17.
12 Ezekiel’s vision highlights one reason why our ongoing search for people who are “sighing and groaning” is so urgent. It involves lives. Soon, Jehovah’s heavenly executional forces, represented by the six men with weapons, will destroy those who do not have the symbolic mark. Concerning that coming judgment, the apostle Paul wrote that the Lord Jesus, accompanied by “his powerful angels,” will bring “vengeance upon those who do not know God and those who do not obey the good news about our Lord Jesus.” (2 Thess. 1:7, 8) Notice that people will be judged on the basis of their response to the good news. Hence, the proclamation of God’s message must continue unabated right to the end. (Rev. 14:6, 7) This places a heavy responsibility on all of Jehovah’s dedicated servants.—Read Ezekiel 3:17-19. 1
Again such wording leaves no room for people that aren't responding to the good news, aren't getting baptised (context shows baptism as a JW is what they really mean, not just baptized in some other religon), and aren't putting on the Christlike new personality to be saved when the end comes. Even if some other Watchtower article says something to the contray (and so far, I don't think they have, just the JWs themselves making these appeals), then we simply have a contradiction, and would not the law of contradiction apply as follows?:
A proposition cannot be both true and false or that a thing cannot both have and not have a given property.2
