Joe, I think there is a common thread, a patriarchical perspective that scorns the feminine. Homophobia then is a consequence of the threat that feminine men offer to a male-dominated patriarchal power structure that is at the core of the past millenium of western religion, not just Roman Catholicism. Women in the priesthood also threaten the power structure. The Church has been slow to move away from the patriarchal, but move it will and doubtless be the better for it.
