Dagney, the WT was showing its youthful vigour as a new religious movement when it was still making statements like the above. Its parent religions and movements had the wisdom of age and didn't do that sort of thing any more. The WT was a brash, fresh-faced youth, feeling his oats and out to prove that he was smarter than his parents' generation.
Fast forward to now, and the WT is looking a lot more like the groups it previously condemned.
