Never mind that this is very close to Godwining the discussion: There is a world and then some of difference to telling a private company your real name and being physically forced to detail the ethnicity of your entire family to the government.

It's also rampant survivor-bias (although the name of that bias is awfully inappropriate in this context). Plenty of countries did (and still do) plenty of registration of citizen's private data without subsequently mass murdering them.
