Pick your battle or fight for every scrap?

So we had a computer glich several days ago that I erroneously attributed to a forwarded email that we received from a friend of a family member that also uses our computer. Even though The glich was not caused by said email, I still, as king of my castle, decreed that we will no longer be accepting forwarded emails from anyone that I felt may unknowingly send us a virus or other problems attached to their emails. Coincidentally, 98% of the forwarded messages that turn out to be religious in nature, or chain letter types come from these people.(please note that I take a special pride in "breaking" the chain)

Well once the decree was nailed to the computer desk(figuratively), Hell began to slightly break loose. I was immediately asked if My friends (including the one that sends the interesting porn) were to be included in this new law? "Absolutely not! My friends know exactly what they are sending!" was my reply. That's when a larger chunk of Hell broke free and I decided that my brief reign as king was probably over for that night.

After talking with my trusted and "all knowing of everything computer" IT guy,(my title for him, not his), we both agreed that there is a possibility of a greater percentage of malicious content being attached to seemingly non-threatening emails such as prayer chains and "amazing picture" type emails.

That's when I decided to revisit the discussion armed with that newly found "factual" evidence. I think it took all of 1 minute for the discussion to turn into something slightly uglier and I had to remind my beautiful wife that I was just making her aware of new found information and not looking to fight. I also had some examples of the lack of computer savvy of some of the email senders (ie: emails about attachments with no attachment, emails with all the forwarded info but the actual forward not included, emails with just a closing sentence but no content). 

I don't think my wife is really interested in the stacks of hard factual info that I have accumulated in support of my original decree. I will now allow all forwards entrance to the castle without prejudice. Firewalls and anti virus protection be damned! All I can say is that I am secretly planning the ultimate "I TOLD YOU SO!!"
