Up Yours seems to think EVERY computer should be screening EVERYTHING for EVERY potential malware on EVERY platform.
Yes, IT guys should be checking for it at sensible choke points.
No, end users shouldn’t be trying to eradicate the world of malware when they’re running suitably secured systems but other people insist on using long-promiscuous OSes.
I've just heard from him/her about his/her "mission" with regard to Apple and Apple users, and have decided it's best to let him/her proceed without further comment or advice from me.

Agreed, of course.

End-user (e.g. desktop) machines should only be responsible for self-protection. If, for example, you're on a Mac, I consider it prudent to run something like ClamAV to augment the more limited built-in anti-malware detecting capabilities of OS X itself.
Detection of Windows or other non-Mac malware can be left to the real mailserver -- assuming your desktop does its mail receiving and sending through one.
As a user of Unix systems since the mid-1980's, I have a very good feel for the inherent security and stability of the BSD UNIX that forms the foundation of OS X. It's the primary reason my central home system (the one I'm typing on now) is OS X.
But that doesn't speak for the upper-level Mac and third-party applications that have nothing to do with Unix, such as my third-party mail client and browser. It's more for their sake that I run the ClamAV. It's very lightweight, and has no discernible negative impact on my use of the computer (and yes, I develop software on it).
However, YMMV and I acknowledge your right to do as you please with regard to how you configure your machines and their protection.
