Sign language, like any language, is a tool for communication and should be used with respect and sensitivity. It's important to remember that words and signs can have different meanings and interpretations depending on the context and the person using them.
Instead of focusing on someone's physical appearance, try to use sign language to communicate positive and respectful messages.
If you're interested in learning more about sign language, I encourage you to find a qualified teacher or resource that can help you understand and use the language respectfully.
