An opinion is not defamation
A defamatory statement is a false statement that harms the reputation of an individual, business, product, group, or government. A defamatory statement must be a claim of fact. If the statement is an opinion, it is not considered defamation. For example, if someone states that a model is ugly, the statement is an opinion and cannot be defamatory. However, if the person says that a model weighs a certain weight or has an eating disorder when neither of these is true, this could be considered defamation. If the statements lead to the model losing their job, the model may have a case for defamation
