Now That's Just Crazy Talk

the preamble to an online survey that i just completed for my employer states, in part, ".  Responses are confidential and anonymous and cannot be linked to individuals.  "

yet at the end, some of the questions were of this nature:

do you work mostly in direct patient care or non-direct patient care?
what is your age rage?
what is your gender?
how long have you worked at this facility?
what is your degree level?
ummm....
if i were to answer honestly to those questions, you would know EXACTLY who I was.
did I answer those honestly?

THAT is just crazy talk.
