"As a Protestant, I'm glad my clergyman is married and has a family, so he can more fully understand his work and the people with whom he works."
Your statement betrays a misconception held by many Protestants: that all Catholic Priests are unmarried. It also ignores the existence of Deacons.
There happen to be many married Priests in the eastern Catholic churches, although this is not the norm in the U.S. There are also men who, having become widowed, become Priests. It's not that unusual.
Most Deacons are married, and in the western (Roman) Catholic church, Deacons are often the de facto clergy for a specific Parish.
Your statement implies that a clergyman who is not married cannot fully understand his work and the people with whom he works. Have you considered, however, that celibacy might be something of an advantage because you can more objectively evaluate what you see? Even if celibacy were a disadvantage, a point which I do not concede, there are plenty of married clergy (e.g. Deacons) available in the Catholic churches.
I'm aware of the married priests in the Eastern church, and I'm aware of Deacons (I'm Episcopalian). I was merely expressing an opinion. Celibacy is of course a discipline that some choose to adopt; it's not (again, my opinion), the normal human condition.
It's just one of many reasons I'm not Catholic.
