Whatever you think about 'The List', let me just say, speaking as someone who had a very major Orwell phase in their teens, and read the complete collected essays in four volumes: his socialism was insubstantial, inconsistent and unscientific. He was very inconsistent in all his positions, e.g. swapping between pro- and anti-pacifist stances during the outbreak of WWII, making wildly wrong and constantly changing predictions about the outcome of the war (e.g. that Britain would never beat Germany unless there was a socialist revolution in England), etc. And despite his long essay against nationalism he still came out with 'The Lion and the Unicorn' which is basically Nazbol-tier support of english 'partriotism' (because the working class are patriotic!!!!!11) as a vital necessity for a socialist revolution – an essay which he then, in turn, vehemently disowned. There are all sorts of dodgy things about him, honestly. Take this quote from his review of Mein Kampf: 'I have never been able to dislike Hitler.' He had even nicer things to say about Churchill.
I get the impression most of his socialism came from guilt at his upper class upbringing (going to Eton) and his time spent as a colonial policeman in Burma. >People call him english chauvinist, but that was only because of his time and upbringing
Tbh I think you have it arse backwards. His support for 'socialism' seems to have stemmed from his upbringing – it being fashionable, among rebellious upper-class teenagers at that time, to call oneself 'socialist'. His english chauvinism, however, was conscious, and not necessarily a given (there were plenty of intelligent, internationalist-minded communists around, upper class or not: in fact, he engaged in polemics with them).
Apart from the escapade in Spain he was never very active in the socialist movement. He joined the Independent Labour Party, essentially a smaller, slightly more left wing parliamentary socialist party. But he still supported the Labour Party. In fact his main preoccupation – and you see this in his essays – was always literary criticism and (very unsuccessful, until the very end) novel-writing. In his political journalism he just wrote about current events, never particularly insightfully, from a boringly liberal-tinged parliamentary labour party type positPost too long.
