Your obviously new around here, so let me explain the objection.
The objection was never the card, as seen in Europe it is quite useful. The objection was that in order to get the card you had to provide fingerprints, photos, and all of your identity details (Ni number, address, where you lost your virginity, etc.), and this information would be stored on a giant über-database which would be accessible by every government agency, the police, and the immigration service. This information woudl be required by law to be kept up to date, e.g. if you moved and didnt tell the database people you had moved you could face a very large fine.
That i can guarantee is not information you have on your ID card. Nor is the information from your ID card stored on a database in germany that is accessible to the polizei or other government departments.
That is what people objected to. These sorts of intrusive information databases allow the government to track and control and THAT is what people object to.
I hope that clarifies the situation. Welcome to The Reg...
