IMO that being attracted towards same sex is mental disorder.  And afterwards making so much hues and cries in their favor is just trying to come to news without having any quality.  They want to attract people's attention towards themselves because of this activity as they have no other good thing to show to the society.  If they want to perform such unnatural sex they can do it in their room; why to make a noise.  Why disturb other's peace.

I have never seen a dog wanting to have sex with the other dog; it always finds some bitch.  Because dog does not want publicity.
