poli sci is still going to be taught, though i suppose you could petition to have it removed from the curriculum. unfortunately you'd also have to get rid of "liberal studies" as well, as art, writing, and other such subjects are too politically charged to be taught in school either.
every teacher i have had tried their best to teach objective thinking...and I had both conservative and liberal teachers. certainly american schools have issues meeting "test score qoutas", but those aren't politically related.
