What does the "b" in LGBT stand for?

Wow!!  Amazing point!  I'm a little miffed that I didn't realize this sooner.  The "b" in "lgbt" means that there are only two genders!  Yet the glbt community keeps denying this biological fact.

I feel so sad for the members of the glbt community because they are so dedicated to doing what's wrong and will eventually stand before Jesus Christ after they die.  Isn't it wise to prepare for an inevitable meeting with God?
