Sorry Nora, but that is a straw man argument. Of course I don't advocate for slavery, no reasonable person would. Are also you a proponent for married priests and dropping the vow of chastity?  I'm a married male convert that was ordained for over a decade in a protestant church, should I demand that the church allow me to become a priest and that it is abusive to prevent me from doing something I am fully capable of doing and performing? I think not despite my over a decade of theological training at world renowned seminaries.
