The birth rate of any society that will continue needs to be 2.1 children per married couple on average. Our birth rate is 1.8. Because I know how the left thinks, this has nothing to do with race, this is the over all birth rate of all races in America.
If we continue this trend, it may take 100 or more years but we will have bred ourselves out of existance.
The birth rate is even lower in Europe. Russia recognized this problem over a decade ago and tried to give incentives for couples to produce more children.
Islam has the highest birth rate right now at 8.1 or thereabouts. With that kind of birth rate it won't even need to be 100 years before Sharia law is global.
But you just keep thinking that this is an attack on gays if that is all your brain can handle.
