Why is racism still in the community?

Well, I’m sure it’s pretty self-explanatory that racism is wrong and disgusting. Singling out people because of the way they look? How is it different from a person having blue eyes or brown eyes? Why does it matter when it’s skin. We may all look different on the outside, but what exactly is wrong with that? There are beautiful and handsome people of all races. Sometimes I sit in bed and I just wonder; Who was the person that looked at somebody with different colored skin and decided that they didn’t matter and they didn’t belong. Who was the first person that thought they were superior over somebody else because of their race? How did it start? I just can’t even grasp with my mind what goes through racist people’s heads. (Also, I do understand all races can be racist) But, inserting violence towards anybody of Chinese descent for starting covid 19? Those people are not to blame. One person is. (Possibly) Apparently, nobody can come up with an excuse of why they are racist to biracial people or African Americans. No child of ANY race should grow up feeling insecure in their own skin because of this judgemental society we live in. Whether you are Caucasian, African American, Biracial, Asian, Indian, etc. We are all human. All people with feelings. Why should it matter if somebody has curly hair, or straight? Dark skin, light skin, tan skin; brown hair, blond hair, red hair? You don’t see people today experiencing violence because they have green eyes and not blue. What is the difference with skin? It’s simply how we look, not who we are. You are not defined by looks and should not be judged or discriminated against in any way because of your looks. All skin colors and races are beautiful, inside and out. (Not everybody in every race though. Some are ugly on the inside)
