We were learning about this in school. I’d imagine the majority said they wouldn’t do this, but there’s definitely some who thinks it’s a good idea (like my uncle, ahem ahem).
But if you had the option to mess with genes and give you the “perfect” baby and you knew what they would look like beforehand, would you do it? You could give your child “desirable” traits while the children who don’t have those traits are inferior, or you could love your child considered “inferior” by society as they are.
The only thing I would personally use it for is to prevent known genetic diseases or birth defects. This is in line with a talk the wife and I had not long ago. They can now test for a lot known genetic disease pretty early in the pregnancy. We both agreed if a severe one came back on the test we would do an abortion. It’s just nothing something we can probably handle properly, and I don’t want to bring a child into this already harsh world that is made even harder for them.
