I don't want to be too contrarian when I overall agree with you regarding Michael, but people, especially children, often love their abusers regardless of anything because it's all they've ever known.This is understandable. We know that Michael is a very emotional person, and that he was writing for an audience. We've also seen how TLC exaggerated their lives to sell their story, so why would Michael not do the same thing?
If Michael were really as terrible of a person as a lot of people seem to think, wouldn't Jani be refusing to see him too? Jani was drugged up, brainwashed and physically and emotionally abused by Susan, and she still defied her by talking to her father when she was told not to. Jani defied the person with immediate access to harm her to talk to her father. That says a lot more about the type of person he is than his blog did.
Still, I don't think Michael is the monster a lot of people think he is. I think he's a troubled man who got caught up with a sociopath while he was relatively young and is just know learning how to walk it all back.
