Getting back to the basics, this whole discussion has absolutely nothing to do with the personalities and the "worthiness" or even how the public opinion could or should hold importance in how a wife of a king should be referred to.
What we need to do here is separate an institution from the people involved in it. Camilla's title of "Queen" whether or not the word "Consort" is used is in relation to her place now within the "Firm" and the institution that surrounds the monarchy of the UK. If the US had a president that held the office for a much longer time than four years, no matter how many times a sitting president married and divorced, each one of his wives would be entitled to hold the moniker of "FLOTUS" or "First Lady Of The United States".
None of this kerfluffle is in any way indicative of "worthiness" or "merit" or whatever else we want to put on it and lately it's getting Diana people up in arms because Camilla was the horrible "Rottweiler" that caused Diana pain and angst and destroyed her marriage and preventer her from being Queen. Diana is dead and through divorce, became a former Princess of Wales (example of a woman that is divorced legally entitled to use her former husband's title until she remarries. Same with Sarah, Duchess of York).
We need to separate the people and the personalities away from the institution of the monarchy and how it does things. Every single one of Henry VIII's wife was "Queen" until they were done away with or died. Edward VIII gave up his title and position as King in order to marry a twice divorced woman he loved (times and attitudes towards divorce has changed immensely since 1936 in both the institution of the monarchy and the Church of England).
The bottom line is that it always was and in a monarchy where continuity is the glue that holds it all together, legally, a wife of any reigning king will always be his queen. It's possible, and it makes sense to me that although Charles and Clarence House perceived the idea of "Princess Consort" for Camilla a good idea, it then developed into all kinds of hassles doing that. To strip Camilla from her rightful title of "Queen", it would take Parliamentary action and then Camilla would be created with that title *in her own right*. Just as Prince Philip was created a prince of the UK *in his own right*. We've also learned from both Andrew's and Harry's "bad behavior" that the *only* time in modern history of the UK that someone has been stripped of their peerage title is for the reason of treason. Along the lines of treason though, the only one that actually has committed high treason against the monarchy actually *is* Diana in admitting to having an affair with Hewitt while still married to the heir to the throne.

We need to leave emotions and moral outrage and what we feel about certain personages when discussing Camilla's title to be when Charles becomes king. It has nothing to do with the people involved. It has everything to do with how the monarchy works. ?
