I'm noticing alot of people saying things that have already been stated here and in many threads, without giving those people credit or just not reading posts?
Thus, resulting in repetition. Perhaps we should start being more aware. :)
I think he really just meant killing two birds with one stone (not literally ofcourse), and not much into the actual species or their origin etc. He just said it in an even more figurative/poetic way (actually naming two specific birds), as everything Front/BACK says is more so an illustration of a theory or vision. In this case, illustrating a figure of speech with yet another metaphor within, being the capitalized letters.
If you take Front's posts into context without needing to decipher much, what he says makes sense. It's everything we've already come to know, while telling us there is still much more we have yet to find out. Basically, be patient.
