"Don't speak evil against each other, my dear brothers and sisters. if you criticize each other and condemn each other, then you are criticizing and condemning God's law."
James 4:11

Yeah sometimes you might jst say " ohh you so stupid" or "you dumb" for fun, but always saying those things to others can really hurt them. Yeah, you only joking around but always picking on them lower their self esteem. Always isolating them and calling them stupid is jst hurting them even more. Have you ever thought of saying something nice would be nice jst cos' their lower thn you or you can say anything to them, we still human with FEEELINGS!
you might not notice that what you say is hurting them cos' you think they know its a joke but noo its hurts yennoe. you never know what you telling them can hurt them.
THINK BEFORE YOU SAY SOMETHING THAT CAN HURT THEM, or atleast apologize.
