I wouldn't advice creating a division like that. Everyone has their own reasons for being who they are. Sometimes things that work for most people work for an individual, too. The more you talk to people, the more you find that each person is unique, and any perceived "normalcy" is a façade that we all put on to fit in with society.
Sure, not everyone wants to fuck dogs, but everyone is unique in their own ways. And often I find that everyone has the capacity to be any sort of person, but they just be whatever feels most comfortable for them in their environment.
It's not me creating a division. It's neurobiology. There is a neurological reason that most humans are the way they are. Just observe this society.
Most humans are socially obsessed people. They care more about fitting into a group, having strong identification with a social hierarchy/group/organization, they are very tribal, and they have a very strong "Me vs You" or "Us vs Them" mentality. This is common amongst most humans.
Most people today feel the need to identify with some kind of group they can be part of. They also have strong self identification with that group. And because of this, it's very easy for them to hate what is different than them. Just look at religion and politics. How many people have you seen change their opinion about a different person once they find out something different about another person?
I can tell you that I've been harassed, judged, bullied, discriminated against for many things but nothing so quickly by people than when they find out that I'm either trans or autistic. Both of those things signal to most humans that I Am different than them, and the survival based neurology in most people fears what is different. It is part of their base code to ostracize what is socially perceived to be different.
Then there is their obsessions with social things like social media.
You can look at thousands of years of history. Every war is started because one people looks at another, she's something weird or different than them, and that's enough justification to commit to the wars and atrocities that they do.
All the bullying that happens at school committed by kids against other kids they see as different is part of that neurological programming.
Its a very survival based, socialization based programming.
Sure when you take the individual from the group you will see that there is more to them that makes them unique, but you get them in their self identified group and that becomes more important to them.
Then there are people like me, neurodiverse, autistic, who are driven more by being individualistic. Our neurobiological programming is very different than neurotypical people. So different we are that psychology and other autism research attempts have failed to understand us for over 60 years because the neurotypical people trying to do the research can't see that their own neurological biases are getting in the way.
