mocking

I feel as though mocking is a way of admitting ignorance of what the other says or the truth contained within. If you feel that no truth is contained, simply don't respond as it's a waste of energy.

Using drugs as a scapegoat on why someone thinks something that he/she thinks or says is also a way of admitting ignorance. "There's no way he could have thought of that if he was thinking 'right'"
