Are there any really "Good" people?

You haven't defined your terms.

To you, I believe, "good" means "a lot more of the good than of the bad."

To the people who are saying there is no such thing as a good person, "good" means "absolutely good, can be counted on to do good in every single situation, and to have purely good motives for everything he does, at all times."

So with your definition, you are right. With the second definition, which is extreme but is valid, they are right. The two don't even contradict each other.

I'm sorry to hear you excluding any definition but your own.
