> This is like saying that Windows and GNU/Linux are closely related because they both run on PCs, and were both (Windows originally) written in C A better analogy would be its like saying BSD and MacOS (the current version) are closely related because they share lots of common code.

I think the best analogies of the relationships between the religions is: 1. Christianity (claims) to be an updated and enhanced fork of Judaism 2. Islam (claims) to be a bug fixed fork of Judaism with some code from Christianity merged in. > Quite some applications have become ported from Windows to GNU/Linux or vice versa. We are not talking about optional bits, we are talking about things of fundamental importance.
