I hear ya. I did k-12 in Catholic school, we were taught science, we were taught about other religions. I even did a field trip in 5th grade to the Mormon Temple in town before the y consecrated it and it was off limits.
They weren't afraid that we would become "godless" by learning about the world. I applaud them for that.
Those who wish to seek truth are never afraid be exposed to various theories, be they blind evolution, or intelligent design.
It only becomes religion when a theory is put forth as fact.. and that is true whether the theory is I.D. or blind evolution.
I did 1 through 10 in Catholic school....my first lessons in evolution was taught to me be one Brother William, a Marist Brother who taught Biology for 9th graders...and his alias, among us 'young skulls full of mush',(he loved his nickname) was 'Bio Bill'.
