Is it censorship?

According the CBS New York, the NYC Department of Education is considering a list of about 50 words that would be banned from city-wide educational materials used with children (assessments, curricula, etc), for fear that their use could make children feel bad or uncomfortable. "The word dinosaur made the hit list because dinosaurs suggest evolution which creationists might not like, WCBS 880′s Marla Diamond reported. Halloween is targeted because it suggests paganism; a birthday might not be happy to all because it isn’t celebrated by Jehovah’s Witnesses."
