Yet, several decent people do regard homosexuality as wrong, Floo - including some who are homosexual themselves.
As for the evidence you question, you have chosen to dismiss some of the evidence that has been presented - such as the healing of Dorothy Kerin on the grounds that this can't happen from a purely human way of thining. The problem is that you are using one set of undrstandings to dismiss a different set of understandings. A bit like using a chemical formula to prove or disprove a physics understanding.
They are not decent if they regard homosexuality as wrong! It is very sad if a person regards their sexuality as wrong, no doubt it has been inbred in them though the unpleasant anti-gay mob. Oh I do hope Jesus was gay and had an enjoyable sex life, you cant prove he wasn't!
Why can't the body heal itself? It can and it does, with no input from any god. As I have said before so may times, if the sky fairy can heal people why doesn't it get its finger out and do so all the time instead of on a whim?
