Someone extremely ignorant and wrapped up in semi-organised football-related violence who has some symbols they associated (with good reason) with that violence. I think it's possible that they were ignorant and self-centred enough to be ignorant of other uses of the symbols.
Well that is a different argument, I don't disagree that it is possible I disagreed with your previous statement that it was plausible.
The most plausible explanation here is that he was a far right **** bag, he had far right symbols because of this and he knew exactly what they were and that this attack on Jones was because Jones is an (admittedly annoying) leftie and the attacker is a far right thug.
The defence argument that he didn't even know what these symbols were, didn't know what the badges were and only attacked Jones by chance over some spilt beer is just some weak BS they tried on, it isn't plausible.
They were nationalists and capitalists.
They were capitalist in so far as they allowed for private industry (albeit with plenty of state control), they weren't too keen on free markets/liberal economics, weren't very keen on people generating wealth through speculation, weren't too keen on bankers (and all the Jewish associations they tagged onto that).
They also had a socialist element as already pointed out, granted the significant part of that was purged in the event already mentioned but still influences modern day neo nazi groups today, to ignore this, deny it or deflect from it by throwing in some mention of capitalism is silly.
