Well, would say either stereotype or loaded words.
Here is why..
Comparison is a rhetorical or literary device in which a writer compares or contrasts two people, places, things, or ideas
A stereotype is a widely held but fixed and oversimplified image or idea of a particular type of person or thing.
Loaded words are phrases have strong emotional implications and involve strongly positive or negative reactions beyond their literal meaning
Glittering generalities is an emotionally appealing phrase so closely associated with highly valued concepts and beliefs that it carries conviction without supporting information or reason
I hope this helps.
