It is starting to make sense. The YEC'ers see this as a major turning point as we are on the verge of breaking genetics wide open and their wish is to stop the evolution of science before we can do that.
I can categorically say that's not true.
There are certainly some things we'd like to stop. Killing of human embryo's for stem cells is a violation of the sanctity of human life. Two homosexuals combining their DNA to make a child is a perversion and a mockery of God's creation. The rabbit-humans that the Chinese created and then terminated at embryonic stage are an abomination. There are sanctity of human life issues related to genetics that have to be dealt with.
But Curing a genetic disease or curing cancer with a modified virus is a great idea and I'm all for it. Just take excessive precautions so that you don't accidently engineer a killer virus and let it loose.
If you can make a cow that has chocolate milk, go for it. God gave us dominion of the earth and we can use for the betterment of mankind. Just make sure you know what you are doing when you do it. Don't take undo chances with things you don't fully understand.
