Why the need to be condescending with people who wish to engage in a friendly discussion?
As he said, in this day and age, ignorance is a choice. Ignorance is not something that deserves respect. It's one thing to be ignorant privately but to go proclaiming something as a reason to doubt evolution after doing absolutely no investigation (the lack of investigation is apparent because there is plenty of readily available information explaining why the differences in the sexes is in no way a problem for evolution) is inexcusable.
Professor Cofty, where did the first living cell come from? How did it originate?
This is one of the watchtower's favorite tricks - conflating abiogenesis and evolution. Evolution makes no claims about the origin of the first living cell (and if you'll look at Cofty's post, you'll see that he did not either). Again, though, if you'd bother to do a little investigation on your own you'd find that there are several different plausible explanations for this that are backed up by observable evidence. Certainly more convincing than the observable evidence for the claim "god did it."
