Someday this is going to become routine.
Not only for the "pre-removal" of genetically-inherited diseases, but for "custom babies" as well.
You may or may not agree, but once the technology "is there", people are going to use it.
And I sense that any attempts to use the government to prevent such usage may end up being ruled an invasion of privacy by the courts.
But there are going to be unintended consequences, of course.
Fearless prediction:
When (not "if", but "when") the combination of genes or other genetic factors is discovered that predisposes homosexuality in males, watch for a "fix" to emerge that will correct such factors before birth. How many parents are there out there who, with their children, someday hope to become doting grandparents, as well?
