The exclusion of women from the priesthood amounts to sexual discrimination in the workplace. That will be the angle of attack on the Catholic Church. It's coming. Just a matter of time.
Sounds as if this writer wants to "force" Catholicism into submission to the will of the state with regard to this, but is not particularly concerned about other religous traditions who also do not go along with his vision of how religion should operate in a secular state. You notice that there is no mention of Muslim, Hindu, Judiasm and so on. Once again, the Catholic Church is being singled out for a type of punitive legislation that would not apply to ALL religions.
