And when they post the same mutilated quotation thrice?
And how are you so certain that he's wrong? Have you studied biology? Taken the time to get a Ph.D. (as I have), thereby demonstrating that you have a good understanding of the basic science as it stands now? Have you ever undertaken a research project aimed at understanding the differences between two similar species, and then, furthermore, tried to carry out the project while handicapping yourself by refusing to look at any research that touches on the evolutionary aspects of the differences?
Until you have that kind of knowledge and experience about what we do in the biological sciences, you really have no basis on which to call someone who correctly states "Evolution is a cornerstone of modern biology" a liar.

Saying that someone is wrong is not the same as calling them a liar. A person can come to an incorrect conclusion innocently.

Above is the original post, with the response to which I posted.
I regret that I have no idea how your question applies to the issue.
