It would be nice if you could remove your YouTube video that you made regarding the highly respected Mark O’Donnell.
Your false claims and accusation's are not helpful. One youtuber even believed what you were saying and posted his own YouTube supporting your claims. He was advised to do his own research, which he did and found your claims to be wrong. He has since made another video to apologise to Mark O’Donnell and his audience.

It is so important to research and get the facts.
