1. Human behavior is definitely an object. Anything that can be viewed or exists in the material world is.

2. "An idea of an external object cannot exist without that object existing as well." The meaning and statement of this statement are clear and true. If you think they are not, then say why.

3. We weren't discussing meanings in the previous exchange. So don't be coy; it doesn't help your argument.

4. Yes, the Nazis killed the Jews, it wasn't just "people" in general who killed them. Labels are definitely real; they exist in the real world both materially and ideally. And you and others type out these labels into other forms of reality when you type about them. So, I have to ask you, how do you define "reality" and what is "real" and what isn't. Your use of the term so far has been flawed and inconsistent.

5. You can object to the "objective existence" of Germany all you want, it still objectively exists. There is no objective moral authority, since the concept and its "authority" are inherently undecided. There are, however, clearly written and executed laws, so legal authority objectively exists in the hands of those wielding and interpreting it. All the people we have inhumanely executed have particularly felt the objective existence of legal authority.

So, I look forward to your definition of reality and how you decide what's real and what isn't
