My son brought home paperwork today - our public school's football camp

[Coexist]

is Christian. They have Morning Chapel, and he gets a free bible for attending.

I am torn. His entire team will be there - and he approached the coach and told him he is an Atheist. Coach said he doesn't have to attend chapel. But the coach is obviously Christian, or he wouldn't have signed up the team for this one. Do you think he will be ostracized? Viewed differently by his coaches?

He joked about being converted - I told him I didn't care, as long as he remained tolerant.

What are your thoughts?

(on edit: it is a High School, and the football camp is being held at a local university, a 4 day sleep-over camp)
