Demand titles are removed from the Duke and Duchess of Sussex

After the recent release of the book Endgame by Omid Scobie, it's not only a blatant attack on the British Monarchy, but the author has had help, either directly or indirectly from the Duke and Duchess of Sussex....certain information is so private that it can only have come directly from the Sussexes. They seem determined to bring the Monarchy down with their accusations and lies.....and yet still they cling to their titles.
They have made it quite clear that they wish to cause harm, but they also appear to hate the English people as well, so why should they still have their titles, especially as they use them all the time. I understand that it requires an act of Parliament to remove the titles and I and very many other people want the removal of their titles set in motion.
