You don't have to recapitulate the whole year's lawyerly accomplishments. (". . . Then, five threads later, I noticed that an alleged picture of a skull was a picture of a replica of a skull!") This isn't your annual review.
There is no religious horror to posing the true Darwinian logic evidenced in Kipling's Just So stories, it is just not rational to do so.
There's no way to excuse what's going on as a mere rejection of an argument. The situation would not have the stated asymmetry if you were correct.
You see, here's the problem. I pointed out "mistakes", they are really not VadeRetro's "mistakes". You did not make a chart based upon teeth, nor did you make a replica of a skull, nor even first allege that Mesonychus was the "father" of whales, those things were done by others. It becomes inexcusable of the antagonist, when having been shown by a messenger the shortcomings of those objects, that the messenger is then derided by him. Ad Hominems, however subtle, when used against logic, show lack of logic.
Oh yes, we should not say that evolution's facts are false. heaven forbid. We must put all evidence against it in a deep Orwellian memory hole. Of course, that does not apply to you. You still keep arguing subjects you have been thoroughly shown to be wrong about (such as proof for no mammary glands on dinosaurs).
