Not the person you're replying to, but if you are going to make sweeping statements like "you are wrong", you should explain a bit more, because your argument is somewhat too vague to engage with meaningfully. Obviously one can find discrimination anywhere, but I don't think it's as systematic as you seem to imply. Most academics are under considerable pressure to publish or generate results, so e.g. when faced with hiring a postdoc or a PhD candidate, they don't have the luxury of rejecting a brilliant candidate that could be productive for spurious reasons.
