Kristin..While I disagree with your assertion that Rhonda doesn't like to be challenged, I think you may be onto something where Iyanla in concerned. I think it's more likely that Rhonda's more skilled at the "touchy feely pop-psyche crap" that came about in the 60s as evidenced by how many psycho-babble buzz words she likes to throw around.

SIDEBAR: How come Dr. Stan, the real psychologist doesn't feel compelled to use any of those silly words, but the pretend therapists, the LCs, who actually refer to themselves as actually having "sessions", throw them around freely? Just wondering.

If I may expound upon your post for a bit:

Iyanla: Lost child to cancer. Was challenged by her daughter. Was herself challenged as a daughter by her mother in an abusive way. Eventually abandoned by parents and other important family members. Acted out sexually for a while. Had three children out of wedlock while struggling financially.

Of those few things I listed, you could attribute them to pretty much every HG she has worked with leaving me to wonder if she picks the HG or if that is the work of the production staff.

Also, I think it's clear that Iyanla uses the women to work through her own issues with her daughters whatever they may be, but it's clear from her actions on the show, creative editing aside, that those relationships in some way must have their own challenges.
