As are airplanes, cities, and clothing, yet you say you're okay with all of those things. It sounds like you're using "unnatural" as an excuse for your personal prejudices. To answer your accusation, I am in favor of civil rights for all legally consenting people of any ethnicity, sexuality, nationality, religion, or gender. If that is "unnatural" then so be it. I'm also in favor of any "unnatural" thing that improves the quality of life for individuals without harming others.
