Why do some people blame an entire gender for the actions of individuals?

Why do people insist on blaming an entire gender for the actions of a few? A man commits a crime, and the narrative becomes, "All men are the same," or "Men are trash." A woman does something terrible, and suddenly, "All women are liars," or "Women are manipulative." Do you even hear yourselves? This mindset is not just ridiculous it’s destructive. Evil doesn’t come with a specific gender. It comes from individuals. Both genders are capable of good and evil. If you think otherwise, you’re living in denial. Blaming an entire gender is a weak excuse to avoid facing the truth. It’s easier to throw hate at billions of people than to admit that the person responsible for the harm is an individual. But let me tell you: your hate doesn’t make you right. It makes you part of the problem. This endless cycle of generalizations does nothing but divide people further. It fuels ignorance, hatred, and toxicity. So idk why some people does blame entire gender? It's just so immature. It's has nothing too do wiith gender , it's depends on the individual.
