But as Hadley puts it in the piece - "he had the misfortune of being right too early".
It seems that it's an acknowledged issue and, unfortunately, it doesn't always redound to people's credit or reputation.
There's a phenomenon known as 'premature anti-[X]' and two of the best known instances are to have been a premature anti-fascist or a premature anti-Nazi.
‘Premature anti-fascist’ was the name by which the Lincoln Brigade veterans of the Spanish Civil War were known by the US Army in World War Two. This service and knowledge didn't distinguish them for a leadership position, it was counted as demerit on their record.
In John Platts-Mills' autobiography (barrister and post-war Labour MP), he recalls being ‘excluded from any form of normal war service by the stupidities of Bevin’. He noted: ‘An anti-Nazi history, was of no help and to have been prematurely anti-Nazi was a positive hindrance … we were condemned throughout most of the 1930s on the grounds that only Communists were against the Nazis and this hostility carried over into the war years.’
Commenting on (British?) veterans of the Spanish Civil War, Platts-Mills wrote that ‘many lefties who had served in Spain were called up or were accepted when they volunteered. Several more got in only after a tussle with the authorities.’
