Depends what troop your son joins, the strong surviving troops that have more than a dozen scouts & stable funding are either filled with atheists & have a few openly gay scouts, or are run by the Mormons. I know in my patrol alone 3 to 4 of the scouts were atheists (myself included) and it was not an issue. A well run troop is there to teach you life skills and morals to live your life by, like not torturing POWs, not force or encourage you to adhere to a religion.
I would be more fearful of a poorly run or Mormon troop myself, but attending a meeting or two and talking to the Scoutmaster/Assistant Scoutmaster will definitely let you scope it out and get a reading before you give your son a choice of getting involved. I would not deny my own son the opportunity I had in scouting assuming the BSA makes it through the next decade, since it definitely helped me form into the accepting, caring & compassionate person I am today.
