Then you should also say something against all straights that don't want children. Also, last I checked, the birthrate is still rising and becomes a problem in some countries. And it is totally normal for birthrates to decline in prosperous Countries. So, do you also have something against them?
Should we all just suffer, so we produce more children. What's far more important is that the children that are here have a loving family.
And I heard far better arguments as what you said. As all you said was about survival. Which we don't do, we don't just survive. We live. Otherwise, we also should stop doing like playing video games. As that is not important for survival.
Also stop spreading lies. As you said, many things that are scientifically disproven.
And the only problem I see is the way some want to force to use gender language. As that could cause problems as information can be lost, to such a degree that you might not get what the other is saying.
