I would avoid this site as it, and at least one other, is run by a JW who goes by the name CJ Williams who due to admitted psychological health challenges, has been told by his elder body that he does not qualify to serve even as a ministerial servant.
In his own words CJ stated that he suffers from:
...a genetic anxiety disorder, perhaps exacerbated by childhood trauma...
To handle the anxiety, I tried medication for a little while. Unfortunately, it caused me to sleep a lot more, and I ended up missing more meetings than my disorder caused me to. There is little I want more than to make every meeting. I also suffered from a life-long depression up until 2011, which I received treatment for in 2010. For these reasons, I have failed to qualify for greater privileges within the congregation.
CJ developed this and another site where he offers "alternative" yet somehow "supplemental" material designed for Witnesses who feel that going to the elders for guidance is not always enough.
While claiming he now has several people helping him create these sites, it appears to still be the work of this one person. He is far more rude and obnoxious than the average JW, and has grown only more bitter over the years.
So not only is this person a JW, he is not even a good example of one. He obviously visits and reads apostate sites in order to produce material that counters the arguments he finds there. A faithful Witness would never do that.
Some of CJ's sites have "comments" from "visitors" who praise his work, but it is clear these come from CJ.
If the elders in his congregation are aware of his work on these self-serving blogs of his, they have obviously given up on him. I am sure we all remember from our time as JWs where there were those few that really believed but were bad examples and wouldn't accept counsel. CJ seems to be one of these, and it probably has to do with his admitted mental state.
It is therefore probably best to just leave him alone. I don't think he's capable of seeing what harm he's doing to others and his own religion.
