Right, but the entire damn point is privacy protections enable people to be more honest. The entire point is supposed to be good data so we can make informed population wide decisions.
And race is a pretty big one under the current administration which has had hundreds of legal immigrants arrested for weeks to months off of "suspicion" that for lack of concrete evidence could only amount to racial profiling.
Administration doesn't care about race, but conservative in groups and liberal out groups. Race is a sort of proxy drumbbeat to appease the most stupid of their base. This is why people like Marco Rubio or Scott Turner are part of the in group despite the seeming cognitive dissonance there. There are a shocking number of black and latino people in this country who do in fact support this regime. There are gay republicans. Muslim republicans. All of this is tolerated by the in group if they are ideologically conservative.
You know how you target best based on ideology? Not the damn census. Social media. What you post, who you follow, all of that stuff we forgot that ICE was getting from travelers at the border imaging their cellphone. That stuff is far more accurate to what you are today, right now, at this minute, and where you fall in light of this regime, and what risk you present to the state and its power structures.
