This might backfire on you because if the person you want to hire has a similar line of thought, he/she wouldn't want to work at your company.
With that said, I definitely understand why an applicant would be offended by the question. In fact, I would hope they are! I guess the second test is seeing if they understand the logic of such a question then convincing him or her that I don't conduct myself this way.
In the right hands, this is a great tool, but in the wrong hands, it is a disaster.
Secondly, it would be setting the bar way too low. I don't appreciate being congratulated for not being an idiot. Someone congratulating me and actually being impressed of that fact makes me think less of that person.
A pretty bad start to a supposedly long relationship, if you ask me.
