I didn’t respond to the census last time; I plan to ignore it again next time.
The census is “allowed” by the Constitution to ask one question: “How many people live here?” That’s it. Period.
It doesn’t matter who wants to ask additional questions. It doesn’t matter how the additional questions are excused or justified.
If you value the Constitution you know the questions aren’t permitted. If, like me, you know the Constitution is only good for showing how far America has fallen, you probably feel no obligation to answer the census anyway.
The “citizenship question” is a red herring.
