It's not a "rationalization" and as stated, OP's own writing was an excellent example. How about a response that actually addresses what's at play rather than meaningless labels like "rationalization".
You don't, which is why you simply responded with a dismissive but non-substantive label "rationalization". Because the observations are facts. Famous white inventors are broadly and profusely celebrated and acknowledged from kindergarten to TV to magazines to college and on and on. Practically everyone has been exposed to famous white inventors which is why OP rattled them off in his post. Ask any random American to list 5 famous inventors and they will all be white men with very few exceptions... because that's what's been drilled into their heads from the day their heads exited their mothers' wombs. Again, yet another fact. As a bonus: A core premise of mainstream "western" culture is that without it, humanity would not have advanced technology, so of course, the lionizing/deifying of white inventors perfectly aligns with that...
Never mind the fact that "western" culture is actually built on, of, from, and by non-European people and cultures. That's to say nothing of the history and present practice of appropriation (taking ownership of) things not self-originated... Never mind that cultures around the globe have had time/condition appropriate technologies before and at the same time as Europe. Never mind the basic fact of how anthropology and all knowledge of humanity's past shows clear patterns that disprove that super-astronomical hubris. I'm sorry that the facts conflict with your desire to self-glorify vicariously with regards to such. I'm also sorry that the facts don't let your straw man of so-called racism against white people by search engines stay together. I'm sorry that you are just an ordinary, non-special plain old human being just like the other 7billion plus on the planet.
