I agree in all of the above, (especially the paranthesis :-) 
One thing that defers Virus from mayor religions is that Virus' view on 
humans it see them more passive (At least in my version, explanation later), 
with exception for destiny-religions. People seeking a religion often looks 
for answers to questions like, how to reach inner serenity, and so on. Virus 
(still my version) says, "You don't really have any free will. You are only 
the result of a mixture of your genes and memes". That fits into my view of 
the world but most people don't have such an objective view of themselves 
and won't like it. Another thing is that Virus is very similar to ordinary 
science, and atheistic people that believe in (general) science and that 
don't belong to a religion often look down on the whole concept of religion, 
including Virus if it calls itself a religion. I don't think Virus fits in 
there.
