Catholic Schools are probably the last major educational institution that isn't completely corrupted by leftists. Despite the stupid stuff that the current pope focuses on, Catholics have been teaching under the same fundamental principles for thousands of years.

BTW you don't necessarily have to be Catholic to go to them. You just have to be respectful of the fact that it is a Catholic school, so you cannot make a fuss about the fact that your kids are going to be taught under a system guided by Catholic theology.
