I would agree with you if 20% of households weren’t being sent the expanded census, plus the outrageously intrusive American Community Survey, which is sent out in non-census years. Your ancestors never had to answer how many toilets their home had, nor answer questions about salary, commute time, medical problems, etc etc.
You are right in that the current short form census does not ask some of the questions asked in previous censuses—notably, they do NOT ask for citizenship status, nor date of immigration. They should. I’d welcome such a question, as it far more salient than some of the other questions.
Is the extended census asking about your sex life? If not, I wouldnt worry about it.
Filling out a census is no big deal. A communist in the whitehouse, is. Focus on him. Not on being counted.
