Hi, Yana. I thought about what you asked me, and I think you could question what philosophy haters think about ethics. Ask them if they prefer the moral codes of ancient religions.
You could start with some of Bertrand Russell's essays, like "The Problems of Philosophy," "In Praise of Idleness: And Other Essays," "Why I Am Not a Christian and Other Essays." Or his "History of Western Philosophy."
If it were possible, I would like to see Roderick speaking about the book "Who Paid the Piper?" It's about how the CIA bought the credibility of some philosophers (it is a fact the agency revealed many years ago). During the Cold War, some philosophers had their careers backed by the CIA. People like Hanna Arendt and many french philosophers were financed by the agency, and that's why they were studied for many decades in the West. The agency did that in order to remove the influence of marxism in the universities and schools. Interesting, isn't it? Even Bertrand Russell was financed, at some point (although he declared himself a socialist).
Pardon my English. It's not my first language.
