In the third issue of The Sovereign Self, the individualist-anarchist paper from Tacoma, WA, Apio Ludd (I believe it was he; not sure; I don't have it in front of me; will edit if necessary) argues against the worship of chaos, not because chaos isn't awesome, but because the individual in order to be free from authority cannot allow a force to exist separate from and above them in a place of sacredness (like God, humanity, etc).
But does that mean Apio--or other anarchists--would critique discordianism? It doesn't sound fun to me to relate to the idea of chaos in the way that people relate to the concept of God, but then chaos is a different kind of force than God is understood to be. God's relationship to humans is usually understood in terms of domination, kingship, paternity (a relation of domination), and historically (while the jury may be out on the chicken-or-egg question of who created who in whose image), the fact is that the social power relations (hierarchies) in monotheistic societies and these societies' religious hierarchies tend to reflect one another. We live in a more "secular" society whose power relations and forms of governance may be more reflective with a humanist belief system--which was the new monster of Stirner's day--or even something else, but in any case discordianism doesn't seem to be the religion of the day. I may have got too far on a tangent there but my point about discordianism is that chaos is not God, and if you look at the sacred discordian texts--lo and behold!--the "worship of chaos" is not at all like the worship of God; the practices reflect the beliefs; actually, the beliefs themselves are self-undermining and ironic, and the whole system seems to be about destroying everything sacred, including itself, in a far more interesting way than rigid reactionary atheism. A major question raised by Stirner's thought is, after all, how one can go about denying these phantoms their place above you. Some of the discordian practices, especially irony and humor, have certainly proven useful to individuals walking that path. Indeed, it would be really silly to say that discordianism is actually about worshiping chaos, even though it is.
Some anarchists say that anarchy is order, and I think they would preemptively reject discordianism but then it might grow on them for its excellent approach to the chaos/order question which would probably lead them to abandon the idea that anarchy is order.
To conclude, I like it a lot! :)
