You should understand the term before commenting. I believe that there are people in this world who have never once been attracted by a member of the same sex but that doesn't rule out the possibility of it happening in thei lifetime and that a majority are capable of being bisexual. I'm one of those people, I was not attracted to any person of the same sex until my very late teens and I've still yet to date one but I wont discount it ever happening even if I were not right now attracted it doest downplay the fact that it could happen later. Yes there are some people who are genuinely. Heterosexual or homosexual but I believe that alot of the world is bias towards certain genders due phycology and to the society and religions they growup in. So saying bisexual is to simple a term. P.s. sorry for the haste and spelling errors, I'm on mobile and its a bitch to type.
