What is the mentality of fat people who like to laugh at others?

Such people generally have no sense of existence in real life, so they will seek poor superiority in others. They are basically unhappy, so they try their best to dig at others, and then others lose confidence in life together. So ignore it. This is very impolite. No matter what others look like, we should respect them. After all, no one can define what people should look like to be beautiful and ugly. Beauty and ugliness can be mutual, not only being thin is beautiful. As long as you are healthy, self-confidence is beautiful.
