Honestly, I can't see what all the fuss is about.
Wayne, your friend sounds like they're making something out of nothing.
Their attitude towards being told that they are wrong is stupid and (unfortunately) all too common.
It's morons like this (without the common sense or wherewithal) to spot a hoax, spam, or chain, email that are resposible in a large part for the rapid spread of viral payloads throughout the world.
If they're not going to talk to you, or email you, anymore then I would suggest that you're on to a winner - that's a few less pieces of crap in your inbox every day
