I do not know of any Catholic Monarchists on this forum - political conservatism (emphasis on individual liberty) and monarchism do not mix well.
Suffice it to say that those who are deeply invested in the idea of the ascendancy of global democracy or the superiority of republican government or the collapse of the Church will not like this book. ;-)
I'm not saying I'm for monarchy in any form, its just that 2000 years of solid Catholic prophecy foretells a return to monarchy, not the ascendancy of republican or democratic governmental systems.
That might be what is behind a lot of these kooky "Catholic monarchy" websites.
