I'm not sure why "cherry picking" is cast in a negative light.
Because you are asking people to accept "truth" from a book, believe in it and worship invisible people whom you cannot describe in any consistent way and live by those standards as a prerequisite for not dying for all time, being tortured forever or whatever, depending upon which part you cherry pick.
When I go out to my orchard I don't reason "Well I've got to eat every apple out there even if it is filled with insects or I can't eat anything!" Pure foolishness.
It is. It's also not at all the same thing as cherry picking the parts of the Bible you believe and would have us believe.
Does an atheist have to accept every thing that Richard Dawkins has ever said or reject everything he has ever said? Or does he "cherry pick" his statements accepting what makes sense and leaving the rest?
Atheism has nothing to do with accepting Richard Dawkins or what he says.
