They tried to take it out at my school. The students said it anyway, and made sure to make, "Under God" louder than the rest of the pledge of allegiance.
Thing is, you can take it out but you can't force the kids to not say it!!!
One time my sister got in trouble for wearing a Jesus shirt. A kid reported her for being "offensive". Another teacher told her to go to the office. Then my mom was involved and the principal did NOT want to open up a can of worms with this topic, so he let her go. She wore the shirt again that week.
