The problem is of course that in some cultures, speaking in euphemisms is so deeply ingrained that the speakers are no longer aware of it.
Opps. I know it's not what you meant, but you should probably make a quick edit.
... and I still find men and women interesting. Why does it always have to be about sexual preference?
Because otherwise it's not a meaningful field. If you're just talking about interest in the sense of "I find people of this sex to be interesting", then 99.9% of people would select "both" and the other 0.1% would just be advertising their misogyny/misandry.
If I ask the wrong guy, I get into a fight. Most straight men are still offended at "being mistaken for a gay man." I can short circuit this by pre-checking something like Facebook.
I'll note that this even happens with freewheeling Discordians who pretend to flirt with men and pantomime kissing them for lulz. Sure, they can flirt with you and everyone else in some outrageous, campy way, and brag about doing anything on two legs with a hole, but then you extrapolate that to mean they're bisexual (omnisexual?) -- and you get genuine and incongruously out-of-character offense.
1. How many people are so harshly prejudice, that they're not even interested in one gender?
2. How many of these people would admit it?
3. Why would Facebook want to know?
4. What does it probably mean?
The fact that someone can deduce what it means doesn't mean it's not an extremely poor wording. A user shouldn't have to go through your 4 questions to figure it out. There shouldn't be any confused-user results when searching for "facebook 'interested in'" online (and there are).
Considering that, it's probably better to leave it open to local interpretation.
I'm Zuckerberg's age and watched Facebook grow while I was in college. For a large majority of people, during the .edu restricted times, it was mainly a way to check if you might have a chance with the girl in your Statistics class.
