Sorry, but reading the article, all I see is a bunch of, what sounds like, liberal wishful thinking. They observed "sexual" behavior... they don't elaborate... what does it mean? My male dog is not gay or bi, however, he has been known to hump my leg. Animals instinctively react to stimulation triggers, it has nothing to do with their "feelings of sexuality." Did they observe these dolphins going to gay bars? Did they observe them making uncomfortable overtures toward straight dolphins? Did they actually observe dolphins having butt sex? My guess is, no... they speculated, based on their own preconceived idea or notion. The gay lobby has been doing this for a while now, the previous argument included 'gay' penguins. What is happening is, liberal mush-brains who want desperately to have something to hang this argument on, have looked around until they found something that appears to support their viewpoint, and they have proclaimed it to be valid, legitimate, and honest... we aren't to question that, else we will branded as racist bigots who hate gays.
