I'm not sure if I got this, but the analogy is roughly this:
One group of people sitting around a fire made from oak logs. The oakies like pork, or indeed any other meat. The preparation of their feast appears to be well underway
Another group are sitting around a fire made from pine logs. Due to some tradition or religion or something, they will only eat certain types of meat, sanctioned by some 'higher power'. However the hunting party who went to fetch their special meat keep sending messengers back telling them that the meat won't be there for another couple of hours. They have been waiting quite some time for their meat, but its special, and conforms to their tradition. A few of them are getting hungry starting to wonder if they should go and and join the oakies.
There's another group that's not quite as advanced as the others - they're still eating berries and vegetables like everyone was doing over ten years ago. They're living in the past, but they're happy. A few of them have wondered about joining with the advanced meat-eaters, but have seen all arguing that goes on between the rival factions.
Finally, there's a group who have central heated houses with devices called 'cookers'. They care little for traditions, in fact they don't even know anything about them, whilst the other groups are experts in their fields. Whether it be the oakies, the fussy meat-eaters or the berry-gatherers, they all know a little bit about the process involved in getting food from the field to the table. These people with the fancy 'cooker' however, eat genetically modified, mechanically separated, glutamate enchanced 'meat', and are happy. Most notably because of two reasons - they are in the majority and their way of life is well-supported, and they are ignorant
I know I've probably omitted loads of groups, but hey that was my attempt at off-the-wall babble...
Can you see which faction corresponds to which group in RL?
