I can partly understand efforts to fix some of history e.g. if someone says they do not want to read books that try to place one group of people above the other. Things move on. Turkey (Ottoman empire) ruled an urge chunk of the world once, so did Egypt, Italy (Romans), Greece (Alexander the great), Britain, the Moors etc. It all moves on.
Fixating on songs such as Rule Britannia is just so unnecessary! It is a rousing song, a brilliant song, even if it comes with some unfortunate bits of it, possibly glorifying colonialism. The French national anthem is gory, has anyone really looked into the wording of the New Zealand rugby Haka that we all respect and laud as a brilliant battle cry?
I am all for modernisation and making necessary changes, especially if we say we are the ones to do better. But for goodness sakes! LEAVE ‘Rule Britannia’ alone!!!! There are tons of other more useful changes people can go and advocate for! Let’s stop the silliness!!!
