That's the thing, though: no matter how you slice it, life isn't simple. We've tried our best to make it seem that way because it's easier to do so than have to think and ascertain the nature of individuals rather than groups.

There are two groups of people, and that determines what their interests are, what clothes they wear, what hairstyles they have, what toys they play with, what jobs they go into, how they interact and how others interact with them, who they should be intimate with, how close a friendship they can forge with certain other people in their group or outside of it, what names they have. All of these things so that when we see a person walking down the street, we immediately know how to classify them... without having to think about it.

Well, somehow sexuality is a defining factor, so maybe we have 4 different groups of people now, but we can easily classify them by how they talk or dress or act, so we can still find a way to keep people easily definable.

However, I disagree. To quote a somewhat maligned phrase from an old favorite of mine, "Infinite Diversity in Infinite Combinations." We're individuals, not male, not female, not gay, not straight. We are ourselves. You're the only Warbler there is. I'm the only Gaffer Tape. To constantly wedge people into a one-size-fits-all mentality, I feel, is to the ultimate detriment of humanity because it immediately and irrevocably limits us for the sake of maintaining an arbitrary classification that someone else created. For the sake of simplicity.
