He "knows" how I voted the same way that the election officials "know"
how I voted with the paper ballots. Or did you think they can't look
at those, too?

We use mechanical machines. But were we to use a paper ballot, I would
not hand it over face up. I would put it in the ballot box. The
operator does not have to see what's on it. The ballot box is locked.
Sure, the operator could sneak it open, but that would be a fairly
obvious action, and would require him to figure out which ballot was mine.

He didn't look at it in an attempt to see how I voted.

Probably not. Most people wouldn't even be interested. But in certain
election situations the prospect that one could could serve as
intimidation of certain people.

he has no idea who I am

That's not always the case, and wouldn't be the case if it mattered.

Until mandatory IDs are required to vote, the system is an
utter sham.

Mandatory IDs have their own problems. What about the voter signing on
a form (like a petition) in order to vote? If the losing party wants to
claim voter fraud, the signatures could be matched up. (Otherwise it
doesn't matter).
