I don't think students are the right audience for "informed debate", since they go to school to become informed. Sure, you can (and should!) simulate informed debate in class, to train students in the method, but the value that teachers add is that they curate the topics and can provide arguments and answers.

Eventually education turns into an actual search for truth, but that only happens in university where actual research happens. Until then it's all a more or less guided preparation for independent research.
