Antidisestablishmentarianism

The Church of England is the established state church, with King Charles III as its Supreme Governor and 26 bishops sitting in the House of Lords so there is a close relationship with the state which means that as an establishment, the state can withdrawal it's recognition known as disestablishment which will annoy some churchy types who will try to oppose it which is called antidisestablishmentarianism.
Yep, i had to Google all that but the serious point is that as Church numbers fall to unsustainable levels, why is the Church of England still holding such sway over matters when only a small percentage of us actually pay any attention to it?
So to some antidisestablishmentarianisers (made up word?), they don't believe that establishments such as the CoE should be disestablished but if many of us had our way, we would remove all traces of religion from having any representation with the State which makes them supporting  prosestablishmentarianism i guess but whatever, it isn't going to happen so it's all actually floccinaucinihilipilification but at least having  a word like antidisestablishmentarianism bandied around annoys the people with hippopotomonstrosesquippedaliophobia, and that's worth something.
