Ah well! Best we stop all education and health profiling then!
So covid vaccine for the first in the queue
All sorts of initiatives open only to those who can read the detailed academic reports, in English (or language of the country you are curetly living in).
Yep, it's all positive discriminarion and that's a form of discrimination in itself, so stop it!
Alternatively OP, you and your well educated husband, working class roots and all, could think it through and come to understand that the questions are there to help people who are not as lucky, educated, well off, etc etc as you. THEY would have benefitted by having their responses link them to all sorts of additional help and support that you simply don't need.
Your complaint would best be phrased that the person asking the question didn't explain why they were asking rather than the information elicited was a breach of your confidentiality, human rights, dignity or whatever!
