What does Proverbs 22:10 mean?

Other proverbs referred to those who are arrogant and unteachable. This attitude leads a person to sneer at those who disagree (Proverbs 9:7–8; 15:12; 24:9). It's good to seek to educate others and help them better understand God's wisdom (Proverbs 1:7; Matthew 5:16). That includes when having a good relationship with them is challenging (Colossians 3:13), and even if they struggle with sin (1 Corinthians 5:9–10).

However, tolerating a hardheaded troublemaker is not a wise choice, especially over time. Such a person causes angst and arguments. This can even become abusive. References to "scoffers" in Scripture evoke the type of person prone to insults and negative talk. When someone is resistant to all reason (Matthew 7:6) nothing is to be gained by keeping them around. The best choice, then, is to remove them from that group, or discussion, or even that church family. When the troublemaker is gone, much of the trouble goes with them. Some fools (Proverbs 1:22) contribute to others only by providing a cautionary example (Proverbs 21:11).

Occasionally, someone stirs up trouble in a church. Bickering and slander cause deep hurt. If such a person does not accept discipline (Matthew 18:15–20), the congregation may have to excommunicate the troublemaker (1 Corinthians 5:9–13). The New Testament records examples of certain men whose conduct was so harmful to faith that they had to be removed from church life to protect the other members (1 Timothy 1:19–20; 2 Timothy 4:14).
