I've stated how he's attacked others. Learn't much? Not really. There's a lot more to know.
I haven't seen that particular YouTube clip you posted before. If that clip has the whole context of what he is recorded to have said at the beginning, then I would say that he was being a bit out of order, because I agree with the principle which has been put simply and crudely enough:
"Religion is like a penis. It's fine to have one and it's fine to be proud of it, but please don't whip it out in public and start waving it around... and PLEASE don't try to shove it down my child's throat. "
And if the context is correct there, it seems to say that he's doing pretty much the same thing.
However, I'm not sure that the whole context has been captured there, because I've watched a fair few debates with him in before and he isn't rude or condescending or displaying any other negative traits, and that is something that has impressed me because of the idiocy of some of the people who attempt to debate with him.
Citation needed about what you said about him attacking scientists. You also went on to say "his disciples", which, hyperbole aside, his supporters are other people, some of which may or may not be jerks. He isn't responsible for them.
If you mean what do I know about evolution and if I have any doubt about it the answer is no, and that was never an issue, and long before anyone gave Dawkins a second thought.
Based on this sentence alone I presume you mean that you consider evolution to be a 'the facts as we know them', yet you said "there is no scientific fact that he can produce that can convince me about evolution", so I am not sure what you mean here.
