Ehh... lol... I'd think if your theory of homosexuality, genetics, and diminishing birth rate were correct, you'd never see enough homosexuals to have any sort of effect on the overall population.
All I'm saying is that homosexuality could be a evolutionary response.. it's not going to have much effect on the world's population in reality, but that's down to factors such as artificial insemination and closet homosexuality more than anything. Imagine if 5%(?) of the world stopped breeding, though. That's pretty significant.
This is NOT TRUE. According to the "updated" article: 7: The average number of seconds between each birth in the U.S. 31: The average number of seconds between the arrival of each new migrant into the U.S. This is very different from what's in the original quote. I assume it was wrong on CNN's part. It's unbelievable they would make mistakes like this.
