I don't think I can give you an answer. Oh, I could give you Freudian reasons with fancy talk, and that would be right as far as it went. But what you want are the reasons for the reasons, and I'm not able to give you those. Not for the others, anyway. For myself? Guilt. Shame. Fear. Self-belittlement. I discovered at an early age that I was-- shall we be kind and say different? It's a better, more general world than the other one. I indulged in certain practices that our society regards as shameful. And I got sick. It wasn't the practices, I don't think, it was the feeling that the great, deadly, pointing forefinger of society was pointing at me--and the great voice of millions chanting, 'Shame. Shame. Shame.' It's society's way of dealing with someone different.
