Earlier quoted context omitted.
I wouldn't mind that one. That a man in the US and a woman in Japan would get different results for a search for "sushi restaurant" is perfectly reasonable (even if the woman in Japan was searching in English). It's when two people in the same neighborhood got different results for the same search that I said "wait a minute, they're personalizing search results now for ad-targeting purposes" and ditched them. The pot…
When I search Python I should get the programming language but when my neighbour searches Python he should get snakes. That is a valid use of personalised search.
It's good for your mental health to be exposed to arguments you disagree with. Many times they will be bad arguments and you can dismiss them, but it's good to know what the people who disagree with you actually believe. And sometimes, just sometimes, you might see something that makes you realize that it's your own worldview that was mistaken, and adjust your worldview to better fit reality. If your search results only show you echo-chamber results that already agree with yours, you'll rarely learn the areas where you were mistaken. (And nearly everyone is mistaken about some things; the person who is right about everything is a rare creature indeed, and you should never gamble that you're that person).
