When people speak in vague generalities.. and use a lot of abstract terms like “justice”, “morality”, “liberty” and so no, without really ever explaining the specifics of what they are talking about, they are almost always hiding something.
Meanwhile, people who use cutesy, colloquial language, brimming with clichés and slang, may be trying to distract you from the thinness of their ideas, trying to win you over not by the soundness of their arguments but by making you feel chummy and warm toward them. And people who use pretentious, flowery language, crammed with clever metaphors, are often more interested in the sound of their own voices than in reaching the audience with a genuine thought. In general, you must pay attention to the forms in which people express themselves; never take their content at face value.
