Because it turns science into a popularity contest. Unlike other disciplines, science has objective truths. A theory is correct or it isn't correct. Evolution is occuring whether we want it to or not, and that's what 100% of the available evidence shows. Our opinions on the subject are meaningless. Just teach the facts.
Science changes all the time - why won't you admit evolution is not written in stone and that scientists don't all agree with all evolutionary theory teaches. Why won't you have an open mind on the subject?
Scientifically speaking one cannot prove, nor disprove that. For those of Faith, that is at least a thought, if not a theory, that is very well worth consideration. IMHO, not to accept the basis of demonstrated evolutionary processes, which by now are darn well documented, is foolish.
But to believe in Evolution as a completely "evolved" body of scientific knowledge, precluding any speculation, including that of an Intelligent Designer, is IMHO equally short-sighted.
So why shouldn't anyone at least know that many highly intelligent, very technically sophisticated people, such as myself, are considering that? Those who do not wish to go down that speculative trail with me may well consider themselves more highly evolved scientifically than I.
OK with me. As far as turns science into a popularity contest, well, I can see your point when it comes to the ignorant amongst us. However, no intelligent partisan of Intelligent Design would turn down scientific evidence, because the more we know, the more we would admire the Intelligent Designer, in whom neither you, nor the scientists presenting their evidence, are obligated to believe.
So to me, those scientists opposed to giving room to Intelligent Design, ought to. They are in no danger of being overwhelmed. Because they do not accept Intelligent Design would be no reason to discount their work!
No conflict here.
