that will never happen.
!_!......how the heck should I know that.....I dunno....I have a gay friend but.....i don't judge.
Use common sense, and think about what you say before you say it.
The number of people who choose not to reproduce will probably always be a smaller number than the number of children people have.
There are not a significant enough amount of gay people to change this.
And it's not like there is going to be a huge rise in the number of gay people if their marriage is legalized.
