1) If I was bi, my fiancee would have a right to know. I'm not saying we'd ever introduce a second man to our relationship or anything (I love her too much to ever share her like that! I want to selfishly keep her to myself!) But at the same time, she deserves to know if I might be more likely to get into trouble drinking with the guys than just hanging with female co-workers.
2) I've had friends admit to being bi before, and I never make a big fuss about it, but I DO WANT to ask questions. I just don't because it would be rude to pry too much. Of course, this is also largely because I'm mature enough to find a man handsome without being sexually attracted to him, so I guess I understand bisexuality's appeal better than most heterosexuals.
3) People who have issues with bisexuals or homnosexuals are living in the past of indoctrinated bible thumpers. Religious texts were written by educated men of the past and warped to give themselves authority. Look no further than the story of Adam and Eve, for example, where it blames the woman (who was made from man) for sin and gives man dominion over her. That was a second story of creation added in addition to the original tale (of the seven days) passed down by word of mouth for generations.
There's nothing wrong with having a strong faith, but people who blindly believe what their elders tell them are the reason for all the fighting overseas. Has anyone else here ever read the Khouran or however you spell it? (I apologize, I AM half asleep.) It's actually a very peaceful religion, but look at all fighting in Afghanistan, which is born from twisting the teachings to control the youth into dying for the selfish causes of the elders. Hell, my step niece is muslim, and her own mother has lied to her about things like their god cutting her legs off if she ever eats pork. Like come on....
Point being, I honestly believe that without the kinds of bigots who use religion as a weapon, the LGBT community would be much more publicly accepted instead of it actually being considered a controversy.
EDIT; Oh, and I forgot to mention, being somewhat into Japanese games and anime, the term "pansexual" made me think of bread, since Pan is Japanese for bread. And then it made me imagine my friends walking around holding loaves of bread in front of their pelvis just to be goofballs. Thank you for that mental image. My imagination is quite weird sometimes.
