Exept learning to love your other.

Eh... I don't think that kind of stuff would work.  Atheists aren't a group in the sense muslims are jews are or whatever, and I'm not sure what atheist history would entail.  I don't think the reasons people don't believe in god should be discussed by teachers.  I have no problem with posing the question to students about whether or not god should be believed in, but no government employed agent should be supplying the answer.

As an atheist I wouldn't want it to be taught in school.  It'd be a total waste of time to me.  I'd rather that time be spent teaching critical thinking, skepticism, the scientific, and the importance of secularism.  Much more important imo.

Not Arabic religions- semitic religions is probably the more accurate word for it.

Jewdism, Islam, etc. Christianity is poked at  in places such as Saudi Arabia(though, Saudi Arabia also kills its own Muslim civilians)

No religion should be taught in USA schools unless it is a private school.  Public schools should be free from religion.  I am a firm believer in seperation of church and state. 

To the op: If you want to learn about other religions then take a religion class in college (I took one that covered all major religions), buy a book, or use the internet.  People shouldn't be forced to learn about a religion if they don't want to.

I've studied Christianity for a pretty long time(7 years in fact). Quite sure I'm not ignorant about it ;)

I've studied from Christians and non-christians. Also, here's the verse:

For if a woman does not cover her head, she might as well have her hair cut off; but if it is a disgrace for a woman to have her hair cut off or her head shaved, then she should cover her head.

To add context, it was referring to prayer only. I seemed to have forgotten to add that. Also, this was the old testament, not the new.

I believe the golden rule covers that. 

But separation of church has absolutely nothing to do with whether or not you teach about religion. That would be like saying schools shouldn't teach about dictatorships since you live in a democracy. But the teaching should be secular in nature, getting students to constructively analyze religions and their social context. Not teaching about religion would be to give religions the freedom to only teach their perspective on the religion as well.

It is absolutely impossible to have a truly firm grasp of history, current events, or literature with no knowledge of religion.  If you don't learn about religion, your education is incomplete.

Matthew 5:17-5:18

English Standard Version
“Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them.

English Standard Version
For truly, I say to you, until heaven and earth pass away, not an iota, not a dot, will pass from the Law until all is accomplished.

There is no concensus within Christianity as to whether or not Jesus' sacrifice fulfills biblical law.  In the sermon on the mount, it seems pretty clear to me that Jesus does not do away with old testament law.

Many seem to believe that Jesus fulfills sacrificial laws, which would seem to make more sense.  

In the early days of the church, it was a matter of great debate.  The basic compromise was that the old covenant still applied to Jews, but new converts did not have to follow the old testament laws.  This is based on pretty flimsy reasoning, but then again, who is going to join your religion if they have to cut off part of their penis?

Of course, it seems that there would be no reason for an eternal god to make laws that were temporary in the first place.  

Well, assuming the people who complained were Christians, I don't see your point (If they aren't Christian then your point is not neccesary).

But, the Jesus in Christainity and the Jesus in Islam are very different. Jesus is the son of God, was crucified, and died in the Bible, and in the Quran, he was only a prophet, and was never crucified and never died. Christians will believe the Islamic Jesus is heretical, and Muslims will believe that the Christian Jesus is heretical.
