Hmm. Interesting topic. I hope I don't come off as sounding superior, but I do feel privileged. I think there's a definite privilege in belonging to a minority, especially if you are also able to pass with the mainstream people as one of them. I feel privileged being a woman, bisexual, poly, multi-racial... Then again, I do think all of the above self-IDs involve a great amount of choice. Not for all people, but I have luckily not been born with an inability to be happy in monogamous relationships.
I feel it's a tremendous gift to be able to observe life from both sides and have empathy for both: mono/poly, straight/gay, white/other... You can see the good and the bad in both, and identify with both communities without feeling you need to declare once and for all for just one group and cause.
