No, I don't think think in general that federal judges are ignorant and biased. You may find a rotten banana in a bunch of them on occasion, but that is true of most anything. If you substituted "YEC" for "federal judge" I might agree with you.
The job of the federal judge in these cases is to listen to the testimony of the expert witnesses and their cross-examination and render a decision regarding the matters before the court.
In the last federal court decision (Kitzmiller v. Dover) on the matters of which we speak the judge said in his opinion:
"Both Defendants and many of the leading proponents of ID make a bedrock assumption which is utterly false. Their presupposition is that evolutionary theory is antithetical to a belief in the existence of a supreme being and to religion in general. Repeatedly in this trial, Plaintiffs' scientific experts testified that the theory of evolution represents good science, is overwhelmingly accepted by the scientific community, and that it in no way conflicts with, nor does it deny, the existence of a divine creator."
