You will not be worried about the baby in it's mother's arms if you crash land on a plane. In reality you don't want to be inconvenience. That's what happens when you live in a society full of different people though. Sometimes you have to wait as they load people in wheelchairs in planes. Sometimes a baby cries.
Today’s kids are tomorrows doctors, engineers, tradesmen, drivers, etc.
Nevertheless, you have made a decision not to have kids and that decision is worthy of respect even if it rests on shaky logical foundations. But you should similarly respect people’s choice to travel with their children and appreciate that as someone who has opted out of that part of the human experience, you have no insight into it and shouldn’t be making statements about disincentivizing parents from traveling with their children. Ultimately, children are just small people. If you can’t deal with interacting with that subset of the population, I suggest you fly private. Or… don’t fly.
