STINKYPANTZ:
You have made a good point. But the quest was if I consider the Watchtower an "inspired prophet". I do not. By "inspired prophet" it is suggested that everything the Watchtower publishes is coming directly from Jehovah or inspired by holy spirit. And this is incorrect.
The "Insight" volume explains the meaning of a "prophet":
PROPHET
One through whom divine will and purpose are made known. (Lu 1:70; Ac 3:18-21) Although the etymology of the Hebrew term for a prophet (na·vi´´) is uncertain, the use of this distinctive term shows that true prophets were no ordinary announcers but were spokesmen for God, ‘men of God’ with inspired messages. (1Ki 12:22; 2Ki 4:9; 23:17) They stood in God’s "intimate group," and he revealed his "confidential matter" to them.—Jer 23:18; Am 3:7; 1Ki 17:1; see SEER.
The Greek pro·phe´tes literally means "a speaker out [Gr., pro, "before" or "in front of," and phe·mi´, "say"]" and thus describes a proclaimer, one who makes known messages attributed to a divine source. (Compare Tit 1:12.) Though this includes the thought of a predictor of the future, the fundamental meaning of the word is not that of prediction. (Compare Jg 6:7-10.) Nonetheless, living in harmony with God’s will requires that the individual know what Jehovah’s revealed purposes for the future are so that he may bring his ways, desires, and goals into line with the divine will. Hence, in the great majority of cases, the Biblical prophets did convey messages that were, directly or indirectly, related to the future.
See, not every single word out of the prophet's mouth was inspired. Certain messages were. The same with the Faithful and Discreet Slave class.
