Have you considered that being openly homosexual has been uncommon for the last 1700 years in western society because christians would kill you for it? Being an astronaut is pretty uncommon. Disease?
Characterizing a persons preference, however odd, as a disease is a bit misleading. Cancer, sickle-cell and schizophrenia actually cause harm, if we grant that homosexuality is rare or "abnormal" it's more akin to having an unusual eye colour.
