Yet you argue the text does not have intrasec [sic] meaning. ... Information is only information because it's interpretated by someone with a brain and there is always always variations, minsinterpretation of intent within it. Because context is something that always infer on the interpretation, and nobody's got exactly the same context at the same time". 

I happen to agree with that statement; text has no intrinsic meaning independent of context. But if that is the case then any combination of words is going to be subject to misinterpretation of intent and all the research in the world is not necessarily going to identify a racist statement removed from its context.
