Heres a great quote i picked up, this may be something for you to think about Alexei...
THE BIBLE SAYS, "DO NOT ANSWER A
FOOL ACCORDING TO HIS FOLLY"
We agree with Proverbs 26:4. We also agree with verse 5 which says, "Answer a fool as his folly deserves, lest he be wise in his own eyes." Either the Book of Proverbs was put together by a madman, or the lesson of the passage is that we have to be careful in how and when we choose to confront false ideas.
Don't just argue with someone who will not listen to reason, or you will be just as foolish as he. But if you are able to show a person the error of his thinking in a way that he can understand, perhaps he will seek God's wisdom rather than relying on his own.
