For instance, you should care that the police is very brutal to black people, even if you are not black and the police acts much better around white people.

Also, he's wrong. It does affect him. All data is analyzed. That includes his data, too. He's just of the attitude that "as long as me or any member of my family which I care about never says anything too critical about the government for the rest of our lives, then we're all good".

In my opinion he's wrong that he'll never be critical of his government. Obama won't rule forever, even if he does like him, and I assume he'll witness at least a few other governments during the rest of his life. Chances are he will become critical of his government, especially if things turn much worse (as the trend is right now). What if the government intends to cut his social benefits? What if the government introduces mandatory army enlisting? And so on and so on. Nobody can stay "non-critical" of the government for too long.

It's also wrong because it's self-censorship: "If I keep my head down, nothing bad will happen to me." The problem is when most people think like that, that's how you end up with tyranny. When little opposition exists, those in power start abusing it.
