Yeah, of course. If he's not a monarch, he won't feel represented by the national anthem. I'm a republican in my country (Spain) and I won't sing my national anthem in years, because it represents something I don't agree with, monarchy.

Of course he shouldn't sing the anthem if he doesn't want to. I just don't get patriotism because no one has ever chosen their nationality they are just born into by the lottery of birth. I'm an englishman but it's only by chance and although i'm grateful that i was born into a developed nation i don't feel that i owe the country anything and neither should anyone else.

Meh. To be fair, it's just words. People barely mean what they say and if one person happens to not want to say something because they dislike it's meaning then I'm fine with it. I wish people would be more honest or upfront with their thoughts. Political correctness with ruin how people interact with each other.

Now i go it

Considering he doesn't believe in God(s) or the Monarchy, wouldn't he be disingenuous by singing it?

I forgot sounds like an excuse, to bad the people weren't more progressive. Religious is never a good thing to mix with governments. It seems to lead to massive corruption that you can't remove from the government without a bloody revolution.

That's the dumbest thing to say. Actually no one knows it, but a large percent of the population believe there isn't one.

Totally agree with you. By extension Patriotism is also saying "I'm better than you because you're different" which is pretty much the root of the greatest evil's in human history.

everything "he" told people in holy books was lies, his morals were primitiv even when they were written down, and he never interacts with the world.  nothing that makes you think uhh maybe this god guy realy exists..

I don't think the issue here was to do with not signing the national anthem per se but the place he was at the time. A memorial for fallen soldiers. Regardless of your view on Monarchy, a political figure is there to pay respects, and many of these soldiers sung that anthem with pride. I mean, he didn't even bother doing up the top button on his shirt.

I don't like Corbyn, and I don't like anthems. So I'm happy that a) he didn't sing it, and b) he's getting shat on for it.

Statism really is a cult/religion, with its "dear leaders", anthems, flags, adherence to traditions, "holy texts". Politicians are just as sex-obsessed and perverted as most religious leaders, too.
