Ken Ham and his fellow young-earthers have done more to drive thoughtful people away from Christianity than Dawkins, Dennett, Harris, Hitchens etc. could possibly have dreamed of doing.
This is demonstrably true. I think it’s too bad, since YEC is just repackaging Price’s Seventh Day Adventist teachings during a brief creationist revival in the mid-20th century. There’s nothing really Biblical about a 6,000 year old Earth.
