Examples of the appeal abound. People say and do anything to gain political power because their genes drive them to do it.
People destroy the planet because it is in their genes to do so.
Capitalism is so successful because it is genetic. I watched a network news program a couple of days ago where born males surgically altered to be females were said to, despite being raised as girls, behave like boys. Being a boy is in the genes, the story went, and therefore gender is not as social as the biological egalitarian thinks. The proof was a scene where one of the girls participating in the study was video-taped playing with army men. She goes straight for the army men.
