I don't think YQ is important enough to warrant an analysis of a lecture given to a lay religious audience. He tends to have a cycle of making offhand ill advised comments targeted towards other audiences which become problematic for his religious followers. For us to now take his faith based self justification and scrutinize it is a bit strange.
While YQ specialized in traditional hadith sciences in Madina that was in the 90s. I am not confident he is really the bridge between secular academia and traditional hadith sciences that warrants all of this back and forth.
If YQ has something substantial to contribute I wish he would do so in writing so that it can be evaluated. I think serious researchers are going to ignore the periodic controversies he sparks.
