In the US voting is not guaranteed to be anonymous. It's protected and (mostly) un-traced to prevent coercion. But the fact you voted is recorded. If you live in a district with few enough voters (or voters who all vote the same way) your voting record could be used to tell who you voted for. I don't think the other ones you mentioned are particularly compelling, no. There are ways to protect the names of people who report crimes without guaranteeing absolute anonymity.
