Most creationists I know are quite comfortable with the observable science of genetics. The fiction that creationists make inferior doctors, genetic researchers, and scientists is something espoused by the more radical and idiotic "intellectuals". Speciation, abiogenesis and many other theories that come under the rubrick of evolution are NOT facts, have not been demonstrated or tested.
Really? Most of the creationists I've heard from do the opposite, and are even more outspoken in attacking the science of genetics than evolution.
When they're asked to cite examples of how the theory of evolution has lead to evil, they immediately begin citing Eugenics cases of the 1920s and forced sterilization of "genetically inferior" people. They seem intent on tying "Darwinism" to this, even though it's a difference science and Darwin knew nothing about recessive genes or inherited traits.
Probably they want to credit "Darwin" to the eeeeeeeeeevil genetics because the actual founder of modern genetics is Gregor Mendel, a devout Roman Catholic Augustinian friar. Mentioning him would go against their talking point that these scientists hate God/Jesus/The Bible, so they attack another non-religious guy (Darwin) who died long before anyone ever heard of genetics.
