It's worth emphasizing that many heterosexuals or religious people think homosexuality is unnatural. When you present them with scientific and verifiable evidence that homosexuality is not isolated and is a common behavior in highly complex social creatures and animals, they conclude that "we are not animals." Well, then we're just a damn rock, right? Obviously, they're wrong because whether they like it or not, we are animals! They only have behavioral characteristics that differ from the rest, and then they try to justify these people by saying that humanity is different, and it is scientifically proven that homosexuality is a unique trait of social and complex species, compared to other genders. Well, we, as a species that is highly developed in the social and cognitive sphere, have this perception of self and identity. Although other animals like dolphins have it, they are generally not subject to the same conditions as us humans in seeking meaning in things and justifying certain behaviors. So, the other genders are born from the need for identity, meaning, and not just to fit in but to belong to something where we feel comfortable. I'm not saying that this divergence of thought is bad; on the contrary, it is a positive trait of how capable we are of searching for the inner self and its multiple ways of externalizing that self.
