Final answer:
Aggression is behavior intended to cause harm or pain. Dehumanization is a step when one group denies the humanity of another group. To combat dehumanization, hate speech should be condemned and hate crimes should be promptly punished.
Step-by-step explanation:
Aggression is behavior that is intended to cause harm or pain. It may involve physical violence against other individuals. For example, two male gorillas may fight and use their canine teeth to inflict deep wounds. Expressing aggression this way may lead to serious injury and even death.
While overt physical aggression towards out-groups is not inevitable in humankind, there does seem to be a universal tendency of humans to be suspicious of strangers
Dehumanization is a step that occurs when one group denies the humanity of the other group, equating them with animals or insects. This dehumanization can overcome the normal revulsion against murder and lead to hate crimes and atrocities. To combat dehumanization, hate speech should be condemned, and hate crimes and atrocities should be promptly punished to prevent further wrongdoings.
