The use of the word "primitive" is revealing. Here is a partial list of things that are labeled primitive as opposed to modern:
Funny, but you never hear love or compassion or altruism or generosity or cooperation described as primitive even though they are certainly as old as the other items. What people are really saying when they use the word primitive is "old stuff that we don't like but can't seem to get rid of." All the energy devoted to eradicating these barbarisms, but they never die. These folks don't know it, but their use of the word primitive is basically making a case for a biological view of man. Show me a behavior dismissed as primitive, and I'll show you a behavior rooted in evolution and biology.
