Walk away from pointless arguments
Allah says, "People loved by Allah are those who walk humbly, and when the ignorant speak to them, they reply with peace." (Al-Furqan: 63)
And, "When they hear useless talk, they just walk away and say, 'You do you, we’ll do us. Peace be with you. We’re not here for drama.'" (Al-Qashash: 55)
Dealing with people who just want to argue or act foolish only drains your energy.
Better to stay calm and move on.
