Sexuality as an identity

We all have an identity. I for example am a White male, computer geek, football player, poem writing person, who happens to be heterosexual. My sexuality is not important to me because it should not be important to anyone else.
What really annoys me is when people use their sexuality as their identity. I had this friend who is a Lesbian. A very smart, beautiful young woman who was so much more, than just the person who was just attracted to other women. I however read her wrong. After a while i realized that she was very proud of being a lesbian, to the point of joining lesbian clubs and groups in her free time. She was a lesbian first and foremost, who happened to be smart and beautiful. This was sad to me because she was so much more. Not saying that being a lesbian is a bad thing, i just think it's bad to focus on something everyone else has to ignore. We can not treat gay and lesbian people differently than anyone else, because their sexuality isn't really our business. This is fine with me, but how do you treat someone who puts such pride into who they are attracted to? Do you go, " Hey, here comes the lesbian girl, i like her because she's a lesbian, beyond that shes a nice person, who is beautiful and intelligent.
If all homosexual people felt like her, it would not take long before we got whole areas of cities where only gay people lived. They wouldn't mingle with us heterosexuals, because we where not part of their little world.
To me sexuality should not be something to focus on. We should focus on what a person is like and what attributes that person possessed. In my mind, sexuality should not even be a subject, just as race or religion should not be. If we start to focus to much on these things, society will become fragmented, with focus on people being different.
Conclusion: Be different by being a good person, by being the best or by being funny. Be different by your attributes not by something as artificial as race, color or creed.
I know my views are colored by my socialist ideology. I don't like people who are different because they are rich, being rich doesn't make for a better person. Having a Ferrari doesn't make you a better person.
Be a nice, smart and beautiful person, who happens to be a homosexual. Not the other way around.
