Personally, I think that it is pretty clear what is meant in that description. However, it doesn't seem to me to be an important issue. The description could remain as it is, it could be changed to reflect your concerns, or it could simply say, "Chocolate Chip Mint Ice Cream Rocks!" for all I care.
If I were to advocate a change (which I am not doing), I would change the description to be more explicit as to what we should expect about the subject matter of the threads that forum contains. Something more like, "Topics should be about the evidence for or against the theory of common descent and/or the role natural selection plays in evolutionary theory, as well as the implications of the theories."
In fact, I suspect that if we get the input of every member on this we would end up with such a range of suggestions that the result would be paralysis preventing any change at all.
Kings were put to death long before 21 January 1793. But regicides of earlier times and their followers were interested in attacking the person, not the principle, of the king. They wanted another king, and that was all. It never occurred to them that the throne could remain empty forever. -- Albert Camus
