As mentioned earlier, secular geneticists know that our genome (And the genome of all primates) is in a downward spiral. We suffer about 150 NEW slightly deleterious mutations and about 3 deleterious mutations which are added to our genome with each successive generation. These are added to the thousands of harmful mutations each of us already have. Natural selection is incapable of detecting and removing these mutations. (Waiting once again for you to say you doubt secular geneticists in secular journals agree)
I think that YEC go to the same sources, and learn the same arguments which no "secular" scientists give a thought to. I doubt that more than a few secular scientists in the world feel the human population is in danger of extinction due to genetic load.
Is it your belief that genetic load on humans is increasing due to lack of natural selection?
Only in modern times with technology, are humans staying alive longer than normal. Throughout the rest of human history, humans died like flies, keeping the world population of humans quite stable and low.
Here is what one secular source concludes.
"... although modern medicine and lifestyle changes have undoubtedly reduced natural selection in some human populations, natural selection still occurs in all human populations. There is scope for selection in the germline cell lineages (Reed and Aquadro 2006), and many pregnancies spontaneously abort (Edmonds et al. 1982). Sexual selection still operates in human societies (Perrett et al. 1999), and this and other factors generate family size variation, allowing opportunities for natural selection. For example, selection associated with variation in male wealth in contemporary populations is at least as strong as selection measured in field studies of natural populations of other species (Nettle and Pollet 2008). Finally, a change in mean fitness could be inconsequential if selection is soft (for example, it might not matter if everyone becomes 5% less sexually attractive). The above considerations lead to doubts about whether deleterious mutation accumulation will produce a detectable fitness loss in humans in the foreseeable future. Less speculative, perhaps, is the existence of finite global energy, food, and water resources. Coupled with expanding human populations, these factors may intensify competition and lead to stronger natural selection in years to come."
