Two homosexuals can never engage in an act of sexual intercourse. It is a simple fact. This act requires complimentary genitalia.
They can only engage in sodomy (oral/anal) and masturbatory stimulation. This is why they are known as "sodomites", from the story of Sodom and Gomorrah.
There are no "transexuals". Just mixed up people who have surgically altered their primary and secondary sex traits with hormones and plastic surgery to resemble a member of the opposite sex. Their DNA will remain the same. They will be unable to produce sperm or menstruate if they have "changed" sex.
Michael Jackson may have bleached his skin and altered his appearance but despite all of his efforts, he is still a black man. We can't change our race, either.
People are going to engage in such practices but it does not mean that society has to accept these outsiders who strive to be different. Our laws don't need to be changed. Our children don't need to be educated in such practices.
I am held (almost) speechless by your admission of sheer, unadulterated idiocy, in every sense and respect of the word.
