JWs don’t want to discuss things in general but especially evolution. I tried to discuss evolution with an elder once and he wasn’t having it at all. He shut that conversation right down. He just said he believes in God and that’s good enough for him, end of story. He’s the sort of elder who regularly makes comments about Jehovah’s “loving” and “wonderful” organisation. You get the sense with some JWs that belief in the organisation comes first and is more important than anything else. More important than defending belief in God even, as illogical as that seems.
I wonder if Watchtower will ever accept evolution? About the same time they accept homosexual people, I suppose. It might take another ten or twenty years.
