I think his answer to the question posed is great! It shows the fallacy of religions as the source of morals. Society and the evolutionary advantage of social groupings are the source of morals, not religions. Religions just hijacked morals because they were a strong method of controlling the behavior of the masses by the religious elite.

I would argue that he did eventually answer the question (stating that secural morality was based on reason, though, discussion, law, etc.), but not until he went off on a tangent about how immoral religious morality is, which wasn't relevant to the question at all. That he started with that indicates either a deep-seater anger/hatred towards religion, or a relatively masterful method of emotionally charging the audience.
Moreover, his popularity is nothing like Hitler's. It's not a cult of personality, he is well known and liked among many atheists because of his intellect. Only the most deluded religious idiot would try to pass it off as a hatefest and that's because those people are basically too stupid to understand his arguments.
It doesn't come across in this video, but I've read some of his books and he IS full of hate. I actually agree with him that civil law should not be based on religion (which, frankly, is part of the foundation of the United States, and I would argue a key point of Christ's, as well as a core tenant of Christianity), but his desire to eradicate religion is unnecessary, hateful, and as much a war-mongering approach as any other fanatical leader.
Non-sequitur
It does not follow that morality is a leap of faith if it is not an absolute.
Furthermore your point is in complete opposition to what dawkins said. His point is that morality should NOT be a leap of faith based on the 4000 year old dribblings of some middle eastern goat header, but instead should be discussed and debated to a rational consensus - quite the opposite of a leap of faith.
Agreed, though his tangent on religious immorality WAS a red herring. He cherry-picked the religious traditions of long-dead religious faiths in an attempt to curry favor with the audience. You cannot judge a modern faith with ancient references.
Yes, this is the question. I think Dawkins was trying to point out that faith is no guide to morality, since it leads one to such strange decisions as killing people for not believing in a certain thing. Rationality is the only truly ethical guide to deciding what actions are more moral. It is only subject to the facts of the situation and an understanding of the feelings and outcomes of the sentient beings involved. Death is nothing to a theist, since it isn't really death, it's just a phase. Death to an atheist is terrifyingly final.
Dawkins often tries to "re-frame" the argument, which I think is what scifes objects to. It's only because the premises of theist arguments are often misguided to such an extent, the arguments against them must address their delusions, not indulge them.
Dawkins statements regarding an unwillingness to engage in absolute morality WASN'T relevant to the question. He did eventually answer the question, but he did a little preaching first.
