"how dare you accuse Her Majesty of being unfaithful to the Lord Jesus?"

You ask "how dare you accuse Her Majesty of being unfaithful to the Lord Jesus?"....please take a look at her coronation oath. See the following important excerpts:
...Archbishop asks queen..."Will you to the utmost of your power maintain the Laws of God and the true profession of the Gospel? Will you to the utmost of your power maintain in the United Kingdom the Protestant Reformed Religion established by law? Will you maintain and preserve inviolably the settlement of the Church of England, and the doctrine, worship, discipline, and government thereof, as by law established in England? And will you preserve unto the Bishops and Clergy of England, and to the Churches there committed to their charge, all such rights and privileges, as by law do or shall appertain to them or any of them?...
....Then the Queen arising out of her Chair, supported as before, the Sword of State being carried before her, shall go to the Altar, and make her solemn Oath in the sight of all the people to observe the premisses: laying her right hand upon the Holy Gospel in the great Bible (which was before carried in the procession and is now brought from the Altar by the Arch-bishop, and tendered to her as she kneels upon the steps), and saying these words:
...The things which I have here before promised, I will perform and keep. So help me God."
The Queen has instead proclaimed and maintained FREEDOM for each to worship any religions, any gods in her kingdom.
The Queen has been unfaithful to her oath to maintain, to the utmost of her power, the Laws of the 1God , the servitude to Jesus His Son, and the true confession of the Gospel.
