Homosexuals are being scapegoated by various members of the Church in an attempt to deflect criticism away from the fact that they've been harboring known molesters of children of both sexes and other criminals for years, but it's "not germaine" to outside commentary?
Sorry, but it became relevant as soon as the scapegoating started.
Now, whether or not a commentator is Catholic is only germaine while discussing the Church's policy on priests -- I really don't think a non-Catholic has any business voicing an opinion on celibacy, banning homosexuals from the priesthood, etc. If the discussion is about the criminal actions of the Church, it's irrelevant.
