You do realize that the Catholic Church originally came out against the smallpox vaccine, saying they were violating "God's will". Now you have people taking ridiculous amounts of fertility drugs, ending up with sextuplets that endanger the mother and all the babies, and religious types go back to the old trope of, "We couldn't choose to terminate any one of these children... it's God's will that we have all of them."
The goal posts on what's ridiculous keep getting moved all the time. I'm not making a value judgement on it -- I'm just saying what is. And to prepare for more of it.
As an old housemate recently told me, who's now the head of surgery for a Silicon Valley medical center, "My job is basically to prevent natural selection." That's true today as it was 200 years ago. When you look at it in those lights, really -- we should be genetically modifying humans 10x over in no time now. We're long past riding the slippery slope, folks.
