Okay, hold on, so I've got:

1) No one trusts a bisexual.
2) Therefore, people who trust bisexuals are nonexistent.
3) However, bisexuals are also nonexistent, so the reason the trusting people don't exist doesn't exist either.

Does this mean that people who trust bisexuals are doubly nonexistent (because not only do they not exist, but the cause of their nonexistence doesn't either) or that they exist after all because there's no reason for them not to? What about bisexuals who trust themselves/other bisexuals? Who's on first?
