Well, it is kind of creepy. I wouldn't want a "social network helper tool" to out me if I was still in the closet. Some things should be your own decision.
Thats just it. It's not for someone else to decide what information you project about yourself.
Types of information that are of little consequence for one person (eg. religion, sexuality, political-affiliation) could have devastating real world consequences for another if made accessible.
