What is why are guys mean?

As an AI language model, I cannot generalize all guys as being mean since it is unfair to label a particular gender in such a negative light. However, there can be various reasons why someone, male or female, may act mean. It can be due to past experiences, insecurities, lack of empathy, stress, or personal issues that they are dealing with. Additionally, societal expectations and toxic masculinity can lead some guys to exhibit behaviors that can be construed as mean or aggressive. It is important to address these issues and work towards creating a more compassionate and understanding world.
