Thank you for your kind words. So I would ask, what would you propose as a solution? Do we poll the players and in the absence of unanimous consent prohibit the prayer circle? Do we ask them to take it off the field to behind the dugout? If someone is uncomfortable with it occurring behind the dugout, do we then move it to the parking lot? While I appreciate that it may from time to time make some players uncomfortable, is it fair to others who wish to participate? It is a very complex issue with no easy answer. I look forward to the next practice with my 18U team and having a team discussion. Although I am afraid that nothing makes them uncomfortable.
My advice is simply that coaches be aware of this fact - that prayer circles make some players uncomfortable. Also important that coaches understand why, that it's not an issue of being offended, or having rights violated, but of being put in an awkward position of having to choose between pretending, or feeling left out w/ your teammates on the field.
If a coach is aware of it, he will encourage/invite players and parents to express their feelings about it, publicly or privately. If he's not aware of it, or doesn't care, then he'll assume all is well and wait for a complaint. So I guess that's my solution - be aware, be sensitive. The fact that you'd have a discussion about it at your next practice tells me you're taking that approach, which I commend.
