Yes, robvalue is right, this is the nature of a discussion. People spend time and brain matter to think about your topic, and it is polite to try as good as one can to clarify terms and what one is talking about in the first place.
The fool hath said in his heart, There is a God. They are corrupt, they have done abominable works, there is none that doeth good.
Psalm 14, KJV revised edition
