he is kind and polite to people of ALL religions whom he reigns over
Well, if so, why can't he be kind and polite to Christians, instead of bashing them, as he's spent most of the last 30 years doing.
You do realize, that as of 2018, only 12% of the U.K. were C of E. If it's over 10% today, it won't be much longer. And of that number, what percent is over 60 years old, and what percent is under 20?
That's CHURCH ATTENDANCE that you're listing percentage about; however, there are also several other Christian sects ( Catholic, Methodist, Baptist, and a few others ) in the UK.
Please list the FACTUAL info concerning King Charles' "bashing Christians for the last 30 years".
I have seen clips of him, for many decades, where he visits ALL kinds of different religious groups and joins in, in whatever is going on, just as he has ALWAYS done when visiting different nations in the Commonwealth. Which is also what Queen Elizabeth II did ALL of her life, even before she became the Queen. It's what they do. In a way, they are "ambassadors" to the nations that they are either symbolic heads of, or when visiting allies.
