Just browsing through the WT publications. Here are examples of the "ones" expression:
sincere ones, interested ones, sheeplike ones, honesthearted ones, new ones, faithful ones, inactive ones, older ones, young ones, deaf ones, deserving ones, violent ones, loved ones, righthearted ones, repentent ones, mature ones, meek ones, loyal ones, little ones, exemplary ones, sick ones, bereaved ones, different ones, taught ones, responsive ones, unsuspecting ones, righteous ones, outstanding ones, afflicted ones, experienced ones, timid ones, baptized ones, needy ones, mourning ones, newly dedicated ones, indecisive ones, haughty ones, anointed ones, wise ones, dear ones, spiritual ones, prominent ones, lowly ones, sad ones, conceited ones, humble ones, modest ones, disadvantaged ones, weak ones, austere ones, worthy ones, victorious ones, poor ones, uninvited ones, perfect ones, upright ones, etc. etc.
There seems to be a real aversion towards using descriptive nouns like "the sick, the poor, the weak," etc. There is almost a numbing effect from the repetition of "ones"....."ones"...."ones"
Yes, that "I'm ONE of Jehovah's Witnesses" is really weird!!! Grammatically, it's sound, but it's always so odd-ball sounding
To me, this phrase stresses the collective over the individual. Saying "I'm a Jehovah's Witness" betrays an individualism that "I'm one of Jehovah's Witnesses" does not. It is a collectivity that is not broken down for the sake of the individual. I checked the past literature and found an interesting pattern. The phrase "I'm a Jehovah's Witness" occurs only once in post-1950 texts:
***

That's quite a striking difference. But even more telling is the fact that the phrase "one of Jehovah's Witnesses" occurs a whopping 2,850 times in the literature, versus a scant 94 cases of "a Jehovah's Witness". Very much a hive mentality at work.
