But again, that article also doesn't tell me what their racial ideology is
So apparently if an article does not tell you what a well known group believes, then it is impossible to know what they believe when they are broaught up. Ok, I guess you are going to join the Provisional IRA because you thought they delivered flowers to British Troops and Protestant schoolchildren, because an article didn't explain their believes when they were brought up.
What a load of shit. Totally Trolling. Common knowledge is assumed when people are reading News. "The Article didn't tell me that Hamas hates Jews!" The Article didn't tell me that Mao was a Communist!" "The Article didn't tell me that the Pope is a Catholic!" "At no point did the article tell me that Bears take a shit in the woods!"
Its basically using the technique of assuming an extremely high definition of the word "Knowledge" and then hiding behind that definition claim ignorance. Its a subtle attack on the whole concept that you can know something.
But, to dip into my Philosophy degree, if you want to play that game, the only thing you can absolutely 100% KNOW is that you exist. Everything else is based on assumptions, interpretation and conclusions based on sensory input. So, sorry, your definition falls flat as you cant claim anything based on anything if you cling to it.
