I tend to agree with Sinis. No offense, but I think you're going about this the wrong way.
I hate to say this--and I know that many on the board are big on the same line of argument as you--but I doubt they'll care about your research. They will only look at each other sadly, realizing that you're not just some weak, crazy, mixed up kid...which all we lesser apostates supposedly are...but you are instead a dangerous individual who must be dealt with for the good of the congregation. Right now, they probably think you just need straightening out, which is (partially) why they promised your wife they wouldn't DF you. Once they realize they were wrong, they will DF you anyway.
Big time.
I know it feels good or even heroic to stand up and fight the power. I think lots of exxers fall into this trap. But in the end, the best thing you'll have to show for it is the ability to claim you did it. Meanwhile, you may lose your wife, your family, everything. Your kids will likely grow up enslaved to the WTS because they'll come to see you as the bad parent who chose Satan's way of life. And all for what?
Is it worth all that for the right to say you stood up just this one time?
Or you could play it smart and make a solid impression on your kids over the coming years, who will realize that every time the WT mags speak badly of worldly people that they are, in fact, talking badly about their dad. Their dad who is a great person and who isn't hedonistic, dishonest, or any of the other crap they keep saying about non-Witnesses and especially former Witnesses.
That's the long path. But it's the best one you've got. It will be far better than some grand courtroom scene that will end if misery. Trust me, it won't go the way you imagine it would.
Dare I suggest that the elders got your wife to dare you to enter the KH to trick you into going there, exposing yourself as an apostate? That's exactly the sort of thing they do at my old congregation. They'll all justify it as their way of helping you. Even your wife. That may not sound like her, but mine did a few things I wouldn't have thought possible of her at the behest of well-meaning elders.
BTW, I'm still married to a JW who worked with the elders "against me" for a time, too. I don't have kids, but I do have some insight on this issue. I hope my advide helps.
