I wasn’t rude to or about anyone.
The golf club membership is obviously traditional and honorary. Refusing it is clearly posturing since golf isn’t a game of ‘the people’ - unlike football (even if Starmer is a real life Roger Nouveau).
A KC with a knighthood is hardly the common man, however he presents himself.
But I can see one positive way to interpret the refusal: historically, golf clubs were notorious for being antisemitic and barring Jewish applicants, which is why Jewish golf clubs started. If Starmer is making a pro-Jewish gesture (like Reeves’s pointed reference in the budget speech to support for Holocaust remembrance) and perhaps subtly signalling his support for Israel, then good for him.
