I think this may be a good point, at first I found the barstool metaphor funny. However, the more I think about it, the less funny it seems to be. It concerns me that some Discordians tend to poke at the sacred cows of others, but in doing so create their own sacred cows (or get a timeshare with someone elses). Smacking people with barstools doesn't really seem to accomplish much (except perhaps getting someone tossed in jail for assault).
The way I see it Discordians tend to fall into roughly three general tendencies when dealing with cabbages.
1. The Erisian sees that the cabbage may become human and tries to awaken them. (They sit on the barstool)
2. The Discordian sees that the cabbage is a cabbage and will play with it until it wakes up or falls apart. (They may dance with the barstool for their own amusement, but might also get a laugh out of the cabbage headed responses)
3. The SubGenius will see the cabbage and think "Mmmmm, coleslaw". (They will likely hit anyone in the room with a barstool if they haven't sent in their $30)
Obviously, these are general labels and not meant to perfectly categorize ALL, Most or even Some Discordians. It's simply a trend that I've noticed. People who tend to see Eris as a archetype or a real goddess or at least are willing to pretend that she is... the mystics among us... also seem to have an optimistic view of humans and the potential for their consciousness. People who tend to see Discordianism as a joke, an absurdist philosophy, nihilism for the acidhead or suchlike, tend to have a less optimistic view of humans (and their fellow Erisians). Finally, the SubGenius element... the Fundamentalist Hawks of our little gang... see the pinks and the norms as a waste of slack... the only value in a human who hasn't converted to Bob is in their $$ and their potential for entertainment at the hands of GWAR or some other insane memory of a bad trip at X-Day.
I think that Bob Wilson and Greg Hill tended toward Erisianism, Hikem Bey probably fits somewhat as the Discordian example and even Stang tends to be more Discordian in his view of the norms than most SubGeniuses. Though most of his 'followers' seem to have embraced the SubGenius philosophy that he preaches, rather than the one that he tends to actively participate in).
But what the hell do I know? I'm a squirrel.
