Identical twins can have different eye color or different hair color. Being identical doesn't mean a perfect match of their DNA strand.Homosexuals will someday be extinct once we discover the gene that causes gay people to be gay. First we can abort them if they have that gene and later we'll flip it so they aren't gay any longer.
Problem solved.
There is no gay gene. It's a behavior that is poorly understood because it became a political weapon for the left to bludgeon christians & rational folks into submission...and they're looking in the wrong field of study to find the cure. There is nothing biological about it as far as the cause...there is evidence that the brain is effected by being homosexual, as well as skin structure & scent change.
Other than that, it's all just lies repeated over and over to you.
How can homosexuality be genetic if there are identical twins, born identical in every discernable way, except one is gay and the other is straight? If you can answer that with evidence to back your assertion with concrete evidence...I will support gay marriage today...donate to causes and everything.
