I don't think everyone needs to learn about it, but I do think that it should be brought up more often. It's a growing case that's making its way through places right now and killing person after person. Some times it dies off into small cases and other times it comes bashing back in big groups. Either way, it's something everyone should know about.
I also think that if the dude wants to talk about this topic, and this is the right forum for it, it should be allowed without members bashing him because it's not a 'cool' topic. I believe this is a very good topic, and could lead to some educated discussions if givent he chance.
