notsurewheretogo: I'm confused as to how Kim's credentials as a lawyer or not has any relevance
I asked this same question when he first demanded that Kim provide this information. I think he is doing it for two reasons: one, he wants to dig into her background and see if he can find anything he can use against her. Two, if she refuses to provide it, he can make that the focus of his replies to her and direct the conversation away from his failings and his failures (which is exactly what he has been trying to do).
As for his foray into climate activism, I agree that it looks like he wants to branch out, now that he has ruined his reputation and limited the already small amount of attention and support he could ever get from JWs and exJWs. The problem for him is that his baggage is not related to the JW organization. He cheated on his wife with prostitutes. He is a terrible person, even to people who are trying to work with him or who want to support him. He is a major drama queen who lives his life online and then gripes that people are minding his business. In other words, he will undermine and sabotage himself wherever he goes, and if he is aiming for a larger and more visible stage, his next self-inflicted wound will probably end his aspirations as a filmmaker.
