You should be very concerned about our House of Lords, our Monarchy and the cronyism and corruption that is currently plaguing our elected officials, and lovely "unelected" advisors to the prime minister such as Dominic Cummings, who's policies used to be followed almost as religious dogma.
You can worry about the "big bad EU" when you understand the EU more.
I'm aware that it is a bold and inflamatory claim to say you don't understand it enough; but I feel confident making such a statement as anybody who has spent more than 20 minutes researching how the EU works would know that it's folly to say that they're "unelected authoritarians".
Lets start with the unelected bit:
EU Commission is elected by Parliment. (IE; indirectly elected)
EU Parliament is directly elected by you, the individual, they are your MEPs, and they're elected in one of the most democratic ways we know of.
EU Council is heads of state (IE; Elected)
Council of the European Union is non-heads of governments of European countries. (IE; Elected).
> neither am I fond of fascists
Might want to look up what that word means, the very idea of a united EU is the opposite of fascism. Fascism is characterised by nationalism.
> governing my community from far away.
The distance between Luxembourg and London is less than the distance between London and Glasgow..
(489km vs 556km as the crow flies)
I'm British, I was a little bit nationalistic before I left the UK and realised that I was foolish.
I'm not accusing you of being a fool but you're certainly misinformed.
I find it's better to not throw stones if you live in a glass house.
