Now I understand where you are coming from. However, I am not advocating finding a "hero" for my daughter, nor do I believe that my daughter thinks of Shane Claiborne as a "hero". She was impressed with what Shane had to say at the event and was moved to tell others about him.
Watching a few videos of Shane concerning helping the poor etc, a lot of what he said is very true. However, they could very well come from some humanists such as Gandhi.
In other words, it is not so much in what he said in the videos that gives him away as heretical it is in studying further into his actual beliefs that cause him to want to help the poor etc. What I found was that he in in a movement called 'New Monasticism" and studying further, I found that Shane had ties to Emergent’s and perhaps the biggest clue was that one of his mentors is Tony Campolo.

I myself don't have any "heroes", mainly because by making heroes out of imperfect people, they set themselves up for error.
However, that doesn't mean there are not people such as yourself that I have learned a lot from. Funny thing is, as I have read even these people, I have yet to find even one that I always agree with.
Yet, one thing remains true about all of them is they point me (if I can put it that way) towards the Lord, as revealed in Scripture. It is also clear that they do not want anyone to take their word for anything, but to be like a Berean and search the Scriptures to see if it is so.
Perhaps if I do find someone to recommend to my daughter, I should put in a word of caution.

Concerning her husband's role in my daughter's life; I do not know where he stands concerning this, mainly because he was not involved in the discussion.
However, if I feel that this is more serious than it appears to me at the moment, because my daughter's husband is her head, I will make sure he gets involved in the matter.
