One thing that inhibits priests in very poor dioceses is the large amount of expensive academic preparation: usually the equivalent of an undergrad degree and 3+ years of graduate school. It takes huge amounts of time and money.
Deacons can be "on the ground" much faster. They aid priests without competing with or rivaling them.
That's what I've seen, anyhow, in our relatively small (population), yet geographically spread-out diocese. I can only reason their usefulness would be even more obvious in the Amazon region.
Those agitating for "womynpriests" have an entirely other agenda: overturning what they call the "gender binary". You'll notice they're generally against Scripture, Tradition, and Natural Law.
A couple of points. Both you and I can baptize; you, being an RICA instructor trains Catechists, and any laymen can provide much in serving congregations that need them.
But what you, I, and deacons cannot do is forgive sins or consecrate the Body of Blood of Christ.
If a bishop cannot cultivate priests and deacons (married or not), what quality of married priests do you think he could cultivate?
