The only point I was trying to make is that if a poll has any spurious nonsense involved that people go with the nonsense. The definition of nonsense is, obviously, subjective which means if something could, even in the slightest way, be construed as nonsense that this is how people will vote. While we're on the subject, I'm also fairly certain that any anonymous poll, whether online or not, will be similarly bad......even if there isn't any nonsense. People like to screw around, but when you invite it............
EDIT: To put it bluntly, if I was presented with a gender specific poll that had Eunuch/Hermaphrodite/Transgender/etc as a gender option I'd probably select it because I thought it was funny. I'd wager (real money) that there are a lot of other non-transgender types that would do that, too (seriously, if anybody wants to make a bet.........).
