See post 95. As for "openly practicing heterosexuals", since the Church has long ordained the widower, that is obviously not true. Your constant attempt to equate the queer with the non-queer keeps running up against reality Deacon. Your seminary formation suffered badly. I am so sorry for you.
A widower with a woman on the side (an "openly practicing heterosexual") will not get ordained.
However, if he commits to celibacy (not "openly practicing") he will get ordained.
Even you can see the difference, can't you?
Like it or not, the Church has always, and continues, to ordain chaste homosexuals.
