Lightbrite – I would definitely say the same thing. Although not necessarily in exactly the same way that he did.
It is important to distinguish between different types of “influential Rabbis”. Some of the people he mentioned are not Gedolim.They are simply knowledgeable people who wrote good books that many people like. You don’t have to agree with everything they say.
When it comes to Gedolim, you can’t disagree with them, but you can certainly say that what they are saying doesn’t “speak to you” especially when it comes to the type of topic being discussed here.
However, in all cases, one must be careful of Loshon Hora. It is assur to criticize a book or a speaker.
Personally, I have certainly found that many speakers do not “speak to me”.
