No it's not the telling her she's wrong it's the way you phrase that. That's what I meant, I thought it was funny.
See I can tell my daughter that that's not why the flowers are all those colours in ways that are less blunt and flat as "your wrong!"
See that is the thing about Dawkins he is very bright but he's also a quintessential science nerd/Mr. Logic at times, or at least that's sometimes the image he has. It's kind of amusing.
And really Honesty may be the best answer in some situations but Blunt and Honest do not have to go hand in hand. In fact just saying "your wrong" isn't even the best way to communicate that fact 
He could have also told her, since she was a child, that perhaps that's ONE of the reasons why flowers are different colors, and then given her the scientific reason. Or perhaps told her that's what some people say and it's a nice idea, but science says......Hell, she was partially right anyway since hummingbirds and probably bees are attracted to flowers of certian colors, but that's splitting hairs.
I agree with you 100%. I'm all for honest answers too, especially with kids. But being so honest that you're just blunt about it doesn't necessarily promote critical thinking in children. Wrong tone and wrong wording, and the kid isn't even concerned about what they're being told anymore, but rather concerned that they've gone and displeased their parent in some way. How are they learning anything then, other than what NOT to say to piss off Mommy and Daddy? If told they're flat out wrong enough times, they might even stop asking questions.
This story is a nice example of how I've observed Dawkins' general treatment of anyone he doesn't agree with. One thing's for sure, and that's a damn interesting biography should Dawkins' daughter ever decide to write one.
