We aren't. Speaking for all Discordians (something that I'm allowed to do), we see Rationalism as part of the larger pattern of Bureaucracy. Discordians view the cycle of existence as having five stages: Chaos, Discord, Confusion, Bureaucracy, and The Aftermath. Rationalism is part of Bureaucracy, associated with villainy, anti-progress, and candid antagonists. None of this is good or bad, it just is; good and bad are our opinions, not a deeper truth.
Now, if you were to talk about Pastafarians, then you'd get a different story; but you didn't, so I won't.
