Go ahead and pull the other one. Catholic teaching is not clear and consistent. Otherwise, you wouldn’t be constantly debating here with each other on the correct understanding of all sorts of doctrine.
But regardless of whether teachings or doctrine remained perfectly preserved and recorded in a clear Universal language since 90 AD or so, in an airless chamber somewhere in the Vatican, you are missing the point. And that is people’s personally held religious convictions are extremely susceptible to change. And people not books, or buildings, or shrines are the ones who are afforded rights.
I find it extremely offensive that a person may deny another the right to express something fundamental to his or her nature, on the basis of a belief that may change next week, if a person decided to de-convert, or convert to another faith.
