If you think that one’s sexuality would be a threat to humanity, you need your head examined. Homosexuality has always existed. If it were a threat, then there wouldn’t be any humans left. There is 7 billion human beings in the world. Add homosexuals, infertile couples, and child-free couples into that equation and you’ll get humanity still populating.
Why is that? It’s simple; there are still going to be couples who want kids, couples who can’t have kids, couples who don’t want kids, and couples who wants to surrogate or adopt.
Let’s bring up four couples.
This is Jane and Dick. Jane and Dick are heterosexual couples who can and want to have kids. Jane has gave birth to 4 little boys and two little girls. They live in a huge house and they’re both good parents to their kids.
This is Tom and Ada, Ada and Tom are infertile. They live together in an apartment, and Ada has decided that they should adopt a kid. Tom agrees, so they’ll adopt children when they are able to support a child.
This is James and Mandy, they are a child-free couple. They do not wish to have children. They spend their lives together traveling and doing things together.
This is Ben and Jerry, they are two gay men. They want to have children, so Ben’s sister gladly agrees to provide them a baby for them to raise. She would visit her baby once in a while. Ben and Jerry raise their son. He grows up healthy, stable, and is intelligent.
All this is happening right now in this world. So what exactly is a threat here?
