Even if we assume, for the sake of argument, that students are being indoctrinated with the correct conclusions on current issues, that would still be irrelevant educationally. Hearing only one side does nothing to equip students with the experience to know how to sort out opposing sides of other issues they will have to confront in the future, after they have left school and need to reach their own conclusions on the issues arising later.This would assume that the goal of education is to produce rational, thinking adults instead of mind-numbed sheeple.
