You literally said if he offends me I have issues or don't understand him. This disregards the notion that you can understand someone as a fellow scientist and be offended by their indefensible interpretations. Sorry but it's not all black or white, and you describing the issue as such makes you more of a zealot than a scientist.
Why would you be offended by the science of a scientist? Let alone their opinion? Why does he offend you so much? I would put this person in the "has issues" category. Not saying that is bad. But it doesn't make you right. Instead, we should focus on the issue. What about what offends you so much? Btw there are plenty of videos of him confronting exactly this.
Nothing is indefensible. Challenge him all you want.
His views are his views. Most of his lectures are about other people's work. When he draws conclusions his logic is sound and his premises are transparent. Talk, think, debate.
