Ah yes, but that right there is the crux of the issue, isn't it?
If it is truly, completely and utterly about religious beliefs, then wouldn't the women and men from the Poly communities (and any other communities) have the SAME beliefs? Why can it be fine and acceptable for the women to play next to gay colleagues each week? If they believe being gay is a sin as a fundamental part of their religion, then surely their beliefs should stop them from playing with and/or against gay players. Acceptance is irrelevant if it is all about belief and faith.
