Your story is amusing. I had a similar experience with the elder's at my hall when I approached them with initial concerns I had regarding false prophesizing and all of the stuff I was reading on the internet. I remember a particular convo I had with two elders, asking them about Beth Sarim. These two were like, "yeah, it happened Rutherford had this mansion he and the rest of the princes were going to reside at after they were resurrected....soooo, and what??" And the PO was one of them and was like a father to me, so I spoke very freely... I was like, "come on dude... this is strange, right?" He just kind of rolled his eyes, smiled, and placed his hand on my back to guide me out of the second school where we were talking.
I figured he would be all, "Now stop looking at the internet, you know how we have cautioned against snares like this".. but instead he just sort of had this nonchalant attitude like, "there there, chrissy you are just out trying to prove to yourself that this religion is false again....haha, what are we gonna do with this one....(points at me & smiles)??"
Sounds like your congregation elders need you to put it in writing with a DA letter. That may be the only way to get through to them.
