Why are gay people more creative?

I just had a discussion with a friend about this and we were trying to figure out why is it that gay people are normally more creative than their straight counterparts, one theory is that gay people have both male and female sensibilities which makes us more rounded and able to appreciate the beauty of life from more than one side or perspective..My theory is that gay people just had to grow up feeling like we were different and so felt that we had to be more creative to stand out and express ourselves, oh and we don't have to spend so much time and energy trying to raise a family so plenty of time to explore other finer things in life..
