> Are you saying that biases and potential biases of people have absolutely no relevance in any "valid" discussion, even in response to subjective observations about why people act the way they do? They have absolutely NO relevance to the argument. Ad hominem is an error in logic. Bias has nothing to do with the argument. It is the argument we refute, not the person. Unfortunately, you It is utterly amazing to me people still argue about these errors in logic. One can only assume it is defensiveness. You might want to look up "straw man" as well. It's another logical fallacy, and you're using it.
