Diversity survey

So I'm filling out the diversity survey, everything's going just fine, and then I get to the question "How comfortable would you feel dating a member of the following groups?" - African American, Asian, etc. So I think really, I would feel uncomfortable dating members of any of those groups, because I'm a married man. So I put my pen to the circle indicating "very uncomfortable." But then I think, no, that sends the wrong message, and I decide that the writers of the survey want me to answer the question as if I'm not married. So fine, I'm not at all uncomfortable dating an African American, an Asian, etc. But then I get to "homosexual or bisexual man." Now there I'm getting a bit uncomfortable, so I put down "very uncomfortable," a bit ashamed of myself for my homophobia. But all is well, because my next choice is "heterosexual man," and I'm no more comfortable dating him either, so there you go. Now we get to "heterosexual woman," and I say, ok, I'm married to one now so presumably I wouldn't have a problem dating one, so I put down "not at all uncomfortable," though I feel a bit like I've been unfaithful at this point. Now how do I feel about dating a "lesbian or bisexual woman"? Well, I guess I don't actually have a problem with that - I dated a lesbian once and it worked out just fine (until she found out she was a lesbian, that is). And bisexual could be kind of fun, if you know what I mean. But now I feel just plain dirty. I struggle through the rest of the list and finally come upon "an international student." Now though I'm pretending to be unmarried, they know and I know I'm a college professor, so my answer is, I would feel very uncomfortable dating an international student. In fact I think I could be fired for that. So I say "very uncomfortable," but now it looks like while I'll date anyone of any ethnic group or disability, I won't date someone from another country, so I'm a bigot.

I don't know what useful information they expect to get out of this survey.
