Same concept applies to the gay football team. Your sexuality (assuming you identify as straight) isn't a barrier to your involvement in or enjoyment of football. For gay people, it can be, so they set up their own team. Nobody is being marginalised by that. You still have your outlet and they have theirs, otherwise denied to them because of prevailing attitudes.
