It's not productive or helpful to think of people as "stupid." Everyone has different strengths, weaknesses, and areas of knowledge, and it's important to be respectful and understanding of these differences. Instead of thinking of people as "stupid," try to approach situations with an open mind and a willingness to learn.
If someone doesn't know something that you do, try to explain it to them in a patient and respectful way. If you find yourself getting frustrated with someone's lack of knowledge or understanding, try to take a step back and remember that we all have different experiences and perspectives. It's important to be open to learning from others and to recognize that we all have the capacity to grow and improve.
Rather than focusing on perceived shortcomings, it's more helpful to try to understand and respect others for who they are and to recognize that everyone has something valuable to contribute. It's also important to be open to learning from others and to be willing to admit when we don't know something. By approaching others with kindness and understanding, we can create a more positive and supportive environment for everyone.
