Well, last time they had a monarch was over a century ago, and they didn't like him that much either
(they were part of Russia at that point), so I guess not that keen on the general idea. Saying that, I'm not British and I love it, and yes - absolutely nobody quite does it like the British, it really is special, so it is a bit annoying that they don't seem to appreciate it.
P.S. Before anybody jumps on me with 'oh there is a war going on in Ukraine, so they have other things to worry about' - absolutely true, but it will be wise to remember that Ukraine is vast, and huge areas are actually uneffected by the war, and not all Ukrainians that left are actually fleeing the war...
