- I think what Jeff was saying was that a gene for homosexuality must
- necessarily be evolutionarily disadvantageous. Women and men who had no
- desire to have sex with members of the opposite sex would be unable to
- bear children and so unable to pass the gene (or genes) for
- homosexuality on to offspring. Perhaps, one might argue, that the genes
- for sexuality are extremely touchy and the slightest mutation can change
- heterosexuality into homosexuality. This may be possible, but I think
- it is an idea offensive to most.
-
- There is in fact little evidence to support the idea that homosexuality
- is hereditary ("nature made me this way"). The best anyone can come up
- with is a statistical *correlation* between the size of a gland in the
- brain and homosexuality. There is no evidence for causation in any
- form. Also, a twins study with about 50% match-up of homosexual twins
- is often cited as evidence, but of course that fifty percent is not a
- very strong indicator of heredity. Even if we assume heredity, we're
- left with the conclusion that a large percentage were anle to *choose*
- not to be homosexual.
-
- And therein lies the difference between racism and discrimination
- against homosexuals. One is proven to be hereditary and so cannot be
- changed and is not a subject for ridicule. The other seems very likely
- to be a personal choice, and like all personal choices, is subject to judgment.
