"Thus it could be changed at any time."
You mean just like the practice of polygamy in the Mormon Church?
Marajade. How does celibacy which is a legitimate sanctioned life for any Christian single ( priest or not) compare in any way to polygamy? If the Church changes her discipline ( look it up) to allow for married priests she would be changing from mandating one legitimate expression of life to another legitimate expression. She would not be endorsing something forbidden by all orthodox Christians throughout history.
Your anti Catholic bias has short circuited the logic portion of your brain.
