"dsc failed to substantiate his assertion that "many if not most atheists hold up evolution as evidence or proof of the nonexistence of God"."
Depends on what you call substantiation.
I consider myself a responsible, objective observer of human behavior, and that is my observation.
Or, one might say, "All experience hath shewn" that many if not most atheists do that.
Since you don't seem to have been watching over the past twenty years, why don't you start now? The data will soon pile up.
If you were to ask me whether I prefer to trust my lying eyes or some study by birkenstock-wearing, tofu-chomping, limp-wristed, one-worlder gun-fearing pansy-assed chicken chocking globalist metrosexual twinkie-addled Subaru driving Starbucks-sipping Dixie Chicks-admiring godless unpatriotic pierced-nose France-loving left-wing Communist latte-sucking holistic-wacko neurotic vegan weenie pervert college professors, well, that's an easy one to answer.
