I think you underestimate the negative effect the timid, retiring intellectuals have on the image of the church. The boy who never went to a high school dance and now seeks the comforts of the robe in order to escape having to face his sexual demons or support his own livelihood ... not fair, agreed, but it is the image nonetheless. Remember, to outsiders, the Priests and Nuns are the Church.
So you’re talking about the priesthood. I would agree that pastors of parishes should preferably be active, outgoing, stand-up men, but there is a need also in the Church for intellectuals and theologians, and I think the main criteria of priests is that they are orthodox and holy. I detect an anti-intellectualism in your comment that I must reject. I also would not agree that timid, retiring and intellectual automatically means engaging or advocating sexual perversion. That is a different issue entirely.
