@Whimsical Sadist: Science does not have to accept the ideas of religion, but it should not deny them either. Science does not have to accept that God exists because it cannot experimentally show that to be true, but it also should not deny God's existence because science cannot experimentally show God's existence to be false. If you are making any assertions that God absolutely does or does not exist, then you are not speaking scientifically because science must show its assertions to be true through experimentation and logic.

And likewise, if something can be proven or disproven scientifically, then religion should leave it alone. For instance, the earth is billions of years old, and all life evolved from a single common ancestor. Both facts have been affirmed many times through methods of science, so it is not religion's place to say that the earth is six thousand years old and all species appeared then on earth just as they are now. Religion can say that God drives evolution because science cannot disprove that, but it cannot say that there is no evolution, but that is something science can disprove.

I do believe that those boundaries should exist although you are right that they are often crossed on both sides.

And that said, the domain of religion does include morality, which can be used to breed sexism, racism, homophobia, and the like. I just wish that all religions taught tolerance above all else. :/
