seems to imply that gay people are incapable of love. If that's what you are getting at you're wrong. No one is missing out on the human experience because they choose type over the other.
Your words attempt to create a two tier society where straights enjoy a "normal" human experience while the gays have their own, but wrong in your eyes, human experience.
This thought process seems to put people into groups that is unnecessary and leads to discrimination and hate.
