I was thinking, and I have discussed this with my therapist too. I've noticed in myself, and other humans too, people are born with a long list of sensitivities. That's what I call them. And always the same basic categories, I've noticed. Really any human who is different, you are sensitive to. Comedian Norm Macdonald once joked. Macy's in New York City was going to include multi ethnic Santa Clauses. And then the babies would have to sit on their laps. Macdonald joked, that's one way to make all the two year olds cry. But you know, whether that joke was appropriate or inappropriate, it illustrates a point. Little children are born sensitive to anyone who is different than their group. Their parents, I guess. Their parents' ethnicity, I guess in this case. People are also born sensitive to people with physical and mental handicaps too, I've noticed. It's not their fault. We don't blame them because they are babies. I think all people are also born naturally sensitive to violence. And sex too, I've noticed. (The reason why humans are naturally sensitive to sex, as I brought up before on this message board, is because of year-round mating, I think. The Hippopotamus and the wolf only mate once a year, and only that one time. The rest of the year they are not at all thinking about sex. If humans didn't have some restraint with sex, we'd overpopulate. And it would cause social problems too. Like rape for example.) I know I was sensitive to all these things when I was very young. We all were, as I said. Violence used to bother me a lot. Even pretend violence, like on TV and in the movies. And sex too. I used to be offended, greatly I remember, when I just saw a couple kiss on TV. Also, seeing people's feet used to upset me for some reason. I went to my best friend's house once at age 8, and he was barefoot. It was Summer of course. And I demanded he cover his feet. When he refused to, I had his mother make him. Also, oddly death, in any form bothered me. Just dead bodies. Even people who died of old age or natural causes. I wonder if this last one isn't yet a sixth sensitivity. Maybe having to do with the fact dead bodies carry many pathogens and diseases. But when I reached puberty, I lost most of my sensitivities. And some I just modified. I think this is universal. In our culture, we lose most of our sensitivities. And some we just modify, as our culture dictates. Most cultures, for example, think feeling prejudice towards people who are evil is acceptable. In fact, some say it is mandatory. And many cultures think that feeling prejudice towards your enemies would be all right too. (I was also going to briefly say, to go off on a tangent a little. I entered puberty at age 9. I still remember. I got some clear secondary sexual features then. But there really was no change in my mental status. Or any other change physically, really. Then at about age 12, I went thru a second wave of change, also due to puberty I think. I lost most of my sensitivities, as I said above. Horror films used to disturb me. I would avoid them. Then, slowly, I started enjoying them. Not at first. I think at age 13 they still bothered me a little. But by HS I completely enjoyed them. Especially horror films dealing with the macabre. Death and zombies and corpses. Also, FWIW, I did start changing more into an adult at age 12, if that's important. I grew taller and my shoulder broadened, like most people that age.) Anyways, what is that all called, that I described above? I'm onto something with that theory. At least I think. What is the explanation for it all? And did I describe it accurately? Are there any psychologists or physicians on these boards? Would you add anything to what I just said?
