Continued - As for celibacy being harmful, there is no proof it is.  I believe some amount of celibate religious and priests are helpful to certain ministries because they are not as encumbered as married people.  There are many happy priests & nuns & brothers who are celibate and would not marry even if they could.  You do have a narrow view of celibate priests & there is no evidence that celibate priests are less healthy or less happy or more likely to abuse than married priests (in fact there is actually some evidence that married men along with men who live in married-like states with women are more likely to a small degree to abuse children statistically).  These are the facts.  Demanding sacrifice does not amount to forcing anyone to do anything.  Part of discerning any vocation is asking yourself are you willing & able to make the sacrifices required.  For example, becoming a dr. will take a person away from family for longer amts. of time over other work-this is sacrifice too.
