Again, the low correlation of homosexual attraction among identical twins does not support your argument. It has yet to exceed 11 percent, which makes it statistically insignificant.
if what you argue were true, then in every set of identical twins, where one twin expresses same sex attraction, then the other must also express the same attraction to the same degree. Since this is not the case, then your argument cannot be valid.
Again I am not arguing for the existence of a homo gene but merely that the author’s argument is bad science.
