Sure it isn't if it doesn't suit you, very convenient. Yet we live in very world completely and utterly in pure 100% mathematical way defined by only our past.
All the crap happened/happening/will happen in middle east and africa? Consequence primarily of european colonialism. Sure we can argue that enough time has passed, entire generations. Yet the places are as fucked up as ever, I would argue even more so.
Or you can explain this to germans who as a nation are still traumatized by what their ancestors did in WWII (shows how decent the core/soul of that nation is... imagine russians in similar situation, they would just blatantly lie about it and imprison/disappear anybody saying differently, like ie Katyn massacre).
Past is a moral argument, like it or not. It isn't a tool to justify anything and I am not commenting on current topic of intellectual theft (which is a rather pointless tea time effort) but ignoring it won't you any good since you won't be able to grok why people or nations behave as they do.
