I think he is admirable.
I don't know much about his personal life but his first wife still uses the surname Dawkins and his last wife & he were divorced amicably. So no criticism there - and no hypocrisy.
He talks intelligently and is an excellent educator.
He pointed out the problems endemic in many faith schools and illustrates the indoctrination that goes on.
He is a man of great integrity and his arguments are very consistent and supported by evidence and reason, not dogma, superstition or religious "teaching". Obviously, he has done nothing illegal or immoral, unlike so many people, whether religious or not.
His comments on rape weren't enlightening, as far as I can see, but he was merely saying that, as with any violent crime, some are "worse" than others. That is consistent with the 'punishment fit the crime' principle. (That is not necessarily the right principle, but that's another topic).
He is polite, reasonable and generally has good relationships with those with whom he debates.
So, criticism of his "comments on rape" is overblown as he is strongly against all rape and probably understands the various motivations for that behavior better than most.
Divorce isn't a failure so much as how his relationships happen to have ended. Everyone who marries believes they will stay together, but life doesn't always go as planned. Divorce is sometimes the best solution.
