Maybe.  It's a shame it's so homophobic in that sense.  Makes me want to see if Blogthings keeps it around or not.  
Don't feel bad for posting it, though - I love taking these quizzes, myself.  I think even the quintessential "Purity Test" online has some bi-sexual type questions - e.g., have you gotten drunk and made out with a member of the same sex even though you're straight? - type stuff.
Most of the people who concoct these quizzes are teenagers or 20-somethings with a lot of time on their hands, I think.  Still, it's a sad commentary on our culture, really, that homophobia is still so socially acceptable.  Really, Blogthings is just reflection, sad as it is, of that.
