What is the key characteristic of aggression in communication?

Aggression in communication is primarily characterized by hostility. This involves expressing feelings and thoughts in a way that is confrontational and often damaging to the relationship between individuals. Hostility can manifest through harsh tones, hostile body language, and a tendency to belittle or attack the other party's opinions and feelings.

In contrast, supportiveness, respectfulness, and assertiveness contribute to healthier communication styles. Supportiveness promotes understanding and encouragement, respectfulness fosters mutual appreciation and avoids harmful language, while assertiveness allows individuals to express their views and needs clearly and confidently without undermining others. Each of these alternatives is key to positive interpersonal interaction, but they do not encapsulate the negative and confrontational essence of aggression as effectively as hostility does.
