Debate also provides the opposing party to test their ideas in the same way. It affords people to explore their own ideals no matter what they are.

There is *tons* of debate to be found in the Bible.

Jesus answered the misconceptions of people who inquired of him constantly. Unbelievers even. He went back and forth with unbelievers on numerous occasions.

Paul did too. And, many others.

It's how we all learn.

We need people OUTSIDE our parameters as much as they need us.

And we are instructed to answer to those who inquire:

But sanctify the Lord God in your hearts: and be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear

But, that says with meekness, not spite.

It is the sprit with which an answer is given that makes all the difference.

Just my 2 cents. Maybe one cent.
