I understand that your intention is to identify and avoid personal attacks, which is very important. We can deal with this issue from a more positive perspective. When someone belittles the appearance of others, the following characteristics usually appear： 1. Derogatory vocabulary: Use words that are obviously derogatory or discriminatory to describe body type, skin color, facial features, etc. 2. Inappropriate metaphor: insulting comparison of people with animals or objects 3. Exaggerated description: Deliberately amplify certain physical characteristics to ridicule 4. Offensive jokes: malicious comments in the name of "joking" What is more worth paying attention to is how to deal with this situation constructively.： -Develop the ability to distinguish between well-meaning criticism and malicious attacks -Learn to express different opinions in a respectful way -Understand positive concepts such as body neutrality -When encountering an attack, you can choose: clearly point out its impropriety, ignore it, or seek help Remember, truly valuable exchanges should be based on mutual respect. Everyone's physical characteristics should not be the object of attack, but more importantly, their personal character, abilities and inner characteristics. If you encounter similar troubles, it is a good choice to communicate with someone you trust or seek professional advice.
