[T.B. Yoits]

And sometimes people might not know for sure if their child will or will not be born with a genetic disease. They only know there’s a chance.

Know for sure?

If they're going in and modifying DNA, they're betting the child would have been born with a genetic disease.

If you're betting against your own DNA, or your spouse's DNA, don't have kids and gamble with their life nor their offspring's either.

[Jamestown1630]

How can you be sure you won’t have children? Every ‘method’ except total abstinence has had its failures.
