Er, don't shilly-shally around here, Wacko. If you think that evolution is not true, in other words does not occur, say so. I contend that it is neither doctrine nor dogma to state that the bleedin' obvious is true. That's my way of using that lovely English word "true" and I'm stickin' to it. My head is atop my shoulders, joined to them via a neck, and that, dear boy, is true (this may also be true for you, but you'll need to remove it from up your botty first so that we can check). But there is no doctrine or dogma involved. You misrepresent Mr Tyson by misusing his remark (which, in the correct context, stripped away here by you, I wholeheartedly agree with). I told you that you were out of your depth. You struggle even to interpret popular science articles, it seems, so thanks for confirming my suspicions.

As I feel that I'm in whimsical mode this afternoon, I just had a thought about those people who are perennially scared of saying that something is true. They sometimes seem to feel that truth is, somehow, too extreme a notion for them to embrace. It's a bit like the history teacher we had at school who never gave any piece of work by even the best kids in the class more than eight out of ten. The top end of the ten-point scale was far too scary territory for him. You could say that the ten-point scale was useless for him, but, had we had, say, an eight-point scale instead he probably wouldn't have ever scored anything more than six. I sometimes used to give ten-on-ten for work that was less than perfect yet had represented perfect effort and resourcefulness. So I say that evolution is true even though there are aspects of it still to be ground out by science (which I've said all along). So, no dogma, no doctrine. And the truth don't scare me! Weeeeee!
