When I first heard the term "Pansexual", it confused the heck out of me. A friend of a friend of mine claimed to be pansexual, what with her girlfriend and all, but in the end there's really only a girl dating another girl. I honestly think with the gay rights craze, people are over complicating things just for the sake of calling themselves other names (Like how Guyver said before). Sex and gender are the same, because once you simplify things it's either you have a dick, a vagina, or in rare cases both, and in the end you either like one or both. By saying you're bisexual, it basically encompasses all the genders, which is why I don't see the point to pansexuality. Everything has a sex, so if you encompass everything with one term then why add another? Sure, you like them for their personality and not what's in their pants. So? That's pretty much what what everyone else does (cept for those hookers out there, but that's a different kind of relationship).
The act of labeling someone's sexuality is really unnecessary, unless you want to attract someone of unconventional gender, in which homo/bisexual suffices perfectly well. Any other reason would be simply to boast your unique sexual preferences, which honestly can't be all that different. If you want to tell people that you base your relationships on personality, well fan-tastic. That still doesn't make you special.
*Left out asexuals since they're such a small part of the population, and if you're not interested at all in the first place then what's the point of getting into the specifics.

You're essentially saying here that we call a square a square, because it sounds different. Therefore, from now on, all squares should be referred to as rectangles because of the small differences between them.
The only difference here is that squares have a much larger part to play in math, such as a number squared. You can't rectangle that number, because the dimensions with rectangles can vary infinitely, while squares remain consistent in their ratio. But that's just my inner math geek blabing.
