Many a parent has stood by their child she is no different in that respect, what do you expect her to do ?
The Queen is different, though - she's the Head of State, Head of the Church of England, Defender of the Faith, Head of the Commonwealth, monarch of millions of loyal subjects, anointed and appointed by God, yada yada.
If she really expects her subjects to go along with the above belief system, then she has a responsibility to set an impeccable example. She can't have it both ways.
I am really disappointed in her lately. I know she's old, but she's either up for the job of being Head of State etc etc, or she's not.
And right now, it's not looking great.
