I note that Mr. Dawkins does not compare language to a "virus" though he admits it as memetic, saving the words with harsher connotations for his ultimate target. He then takes a one-sided view, accentuates the bad, ignores the good, focuses on the least reasonable religious people he can find, and calls it a day. On the internet, we call this "flaming". But hey, at least he didn't bring up Hitler.
Bach? The University? Keeping alive European scholarship during the dark ages? Providing a center for community cohesion and services to the disadvantaged? Not mentioned, of course.
I would even be willing to bet that our beloved secular modern egalitarianism owes its root to Christian philosophy, but that is speculation.
No dispassionate exposition on the concept of memes, this. Mr. Dawkins clearly has an axe to grind.
