No need to reread. I read them carefully and I still stand for what I said about those definitions. The words you used don't forcefully drives them to the conclusions you make.
Denial doesn't mean you're lying consciously. In some cases it may be lying. In other cases it doesn't, because this is a state of mind that you cannot control without help.
Refusal to answer doesn't forcefully mean denial nor lying! What you claim is simply not true because you assume refusing to answer something as being forcefully a denial state, which is not always the cases, so it's not accurate to assume it is, in all cases!
And finally, the other claim is also forced. Ignoring someone's questions doesn't equate to lying. These are assumptions you're making on your own but they don't seem correct to me! At best, ignoring could eventually equate indirectly to denial in the sense that one is not willing to answer. Once again, not willing to, doesn't mean one's lying!
