LGBT is not a clinical description of someone's sexual desires; these are social identities that people earn.

I think I have to disagree with you. The implication that I have to do something that other people respond to before I can Identify as LGBT (which is how I read the word 'earn' in this sentence) is offensive.

Sexual identity is about a person's own take on their own preferences. I am no less gay for living a heteronormed lifestyle. I'm still gay, even if *no-one knows*.
