Separation of Church and Public Education

Separation of church and state has long been a hotly debated issue in the United States. 

Here's an example.  In the state of Texas, intelligent design (based  on religion) is taught along side the theory of evolution (based on  science).  If some conservative Texas state politicians had their way,  evolution would not be allowed to be discussed or taught at all in the  public school system. 

What are your feelings about religion and education?  Should they be  kept separate from one another or is it appropriate to combine the two?   Should scientific findings drive curriculum or should personal  beliefs?  If you feel it is okay to combine the two, which religion(s)  should be incorporated into public education system?  If you believe  only a specific religion or set of religions should be selected, why  should others’ views be ignored or marginalized?
