Instead of saying "you're stupid," you might consider expressing your feelings in a more constructive and gentle way. Here are a few alternatives:
- "I don't quite understand your reasoning."
- "That idea seems a bit misguided to me."
- "I think there might be a misunderstanding here."
- "Can you help me see your perspective on this?"
- "I think we might be thinking about this differently."
These alternatives encourage open dialogue and understanding rather than name-calling.
