Privacy means that no one can see your data, and only you can decide who can see it. Anonymity means that everyone can see your data but no one can match you with the data.
As for the question, yes, I would more than happy when people could understand the risk of giving up the privacy. But I’m afraid that not many people would understand the message carried by those books.
It’s a complex and polarising issue. The main problem is that some, sometimes most, of immigrants don’t want to assimilate. They are creating ghettos, don’t respect local laws. Other issue is that governments prefer to spend tax payer money for accommodating immigrants instead of solving nation’s issues.
I wouldn’t limit immigration per se. I would limit unchecked illegal immigration and spend more money on assimilating immigrants that want to contribute to a country they moved into.
