IMO the words to our national anthem are irrelevant. I’m a devout atheist (admittedly I enjoy having the monarchy, despite them being merely ceremonial. And German/Greek) but whenever God save the queen comes on, it fills me with pride and I sing along, not because of the man on a cloud looking after a German grandmother, but because it’s British, it’s ours, it’s the tune we play when we are proud of what we have/one of ours has achieved. Do you feel the same way when the star spangled banner, advance australia fayre or deutschland uber alles plays? No, because that’s not ours, it’s someone elses ‘proud’ song. If people don’t want to sing/don’t like the anthem, fine. But you are missing out!
And to that m****n tool, do us all a favour, take one for the team, shoot yourself between the eyes. If you loved the monarch and her country so much, at least have the decency to live here.
