Any one who wants to can become a homosexual. Just anyone who wants to do it.
If we follow the ILlogic of homosexuals 70% of all hard core criminals are homosexuals. In the prison population the number rumored to have participated in homosexual sex due to the confinement in a single sex population is 70% (rumored based on best information due to the absolute reluctance of officials to permit a proper study fearing cruel and and usual punishment appeals)
According to homosexuals one act makes the homosexual and those in prison engaged in at least one act. Thus the illogic would indicate that of the 2.7% of homosexuals in the general population 70% are going to become hard core criminals. (2.7% is from the lawrence brief of the homosexual advocate groups, the 10% is now officially abandoned.)
This also fits with the fact that a disproportionate number of child molesters are homosexuals.
