Lots of us do know what the Catholic church really teaches (been there, done that) and we've backed it up from vatican.va. itself.
At the very least, there's a huge discrepancy between what the RCC really teaches and what FRoman Catholics think it really teaches, or what they think it should really teach, or what they wish it would teach, or what they were taught.
That's as may be, but of those who make the loudest claims to know because they are apostates there are many who did not even know about married Catholic priests.
They thought celibacy was doctrine instead of discipline. And when they were told it was discipline they scoffed at the idea and tried to shuffle it off on recent changes though it's been true for hundreds of years that some married men can become priests.
So, I hear the claims, I look at what they say, and I know the claims are not to be believed.
