I have read about it. Her authority is symbolic in nature. Parliament holds the power to make and enforce laws.
"Any people that believe that the Queen is empowered or even approved by God to a position of authority over them deserve ridicule. (That is so 1700s.)"
Well, tell the British folks that you don't approve of their choices. They might listen.
“Parliament holds the power to make and enforce laws.” CA
Yes, and that power was granted to Parliament by ...wait for it...
The Crown.
Parliament can also be dissolved by the Queen. Although that would be an extreme measure, the Queen has the military to back her. As a practical matter, it is unlikely to happen, but that is not the debate.
BTW - My ancestors served in both the revolutionary war, in Washington’s army, and in the war of 1812 with distinction.
