Religion is a touchy subject and should be handled by parents. I agree with the idea that you have to teach pupils bout religion because not doing it is encouraging discrimination and fear but specific advocacy by teachers is wrong. In a lot of countries you can get fired for doing it unless the school is a special religious school - for example France.
This evidence is in the Constitution of the United States of America. This country was founded on religious freedom, which entitles the people to believe whatever they want. They are not to be persecuted for it. However, the classroom is not a grand place for this, because children are meant to learn basic skills, and religion is not one of them.
Now, this does depend heavily on whether this is a private school or a public school. In public school, I believe that this should not be done, no matter what. Let the students have their own religious beliefs, without being messed with by the teachers. In a private school, it would depend on if it is a religious school or not and, if it is, then it would be silly to do so.
I believe teachers should be fired for teaching religion in public schools. Not everybody in the classroom is the same religion and by saying anything about religion could insult students and make for an uncomfortable learning environment for those kids. Church is around for a reason...if you want your kid to learn religion then take them there.
Parents did not send their kids to school to be force-fed religion of some kind or another. Inflicting superstition on growing minds is not the job of the school system, and it is definitely not the teacher's place to attempt this. This isn't the kind of thing that can be solved with a reprimand; only instant firing will do the trick.
Students should have to want to be taught religious beliefs, but teachers should not be wholly restricted from it. If someone in the class objects because of an intelligent, feasible reason, the teacher should not continue in his, her, it's preaching. If the students wish to be taught or have no objection to being taught religion, the teacher should have the option to preach to them.
In most western countries the majority of citizens are Christians, yet teachers are required to hide this. Simple things like celebrating Easter and Christmas are a part of our culture because they are Christian beliefs. Kids see religion everywhere yet they are expected to pretend it does not exist within a classroom.
Children need to make informed decisions in life and they make these desicions by being exposed to various stimuli. Children need to make up their own minds about religion and most will despite what their teachers say. But if religion is not mentioned in the home then they to are getting a biased picture and some exposure at school can help them make a well informed and non one sided desicion.
I think if teachers want to express their personal beliefs in the classroom they have the right to do that. They shouldn't be overbearing, but the amendments to the constitution gives the rights for freedom of speech, and saying that teachers don't have the right to express religious beliefs strips them of the rights that our forefathers set in place! I am only 14 but I care about the way Christians are treated in this day and time. America is trying to keep the religion that put this country together out. I am a Bible believing Pentecostal, and I will do whatever it takes to get the Christians back to where they need to be!
Our forefathers fought that we might have religious freedom, we let one person change out schools. I remember every morning we did the pledge to the Flag and a scripture before class could start. The children today are missing out on a lot because they have not been taught to honor God.
