CMV: Race is only a social construct

Race is only a social construct created to make people hate or be lower than others. I have went to schools that are majority black and some that are majority white, and with both I have noticed it's society that defines race not skin color. Throughout history different groups have had their description of race changed just to be oppressed. Irish 100 years ago were considered their own race, and 150 years ago Mexicans were considered white. The definition of someone's race changes every few decades, and I'm tired of having people be divided because of something that society defines as different. Not to mention these days people are a melting pot of races in their own biology. People need to think outside of society's constructs so that we are together as one instead of just conforming to hate. In my opinion we need to start with race. Thank you

Edit: Had to repost because auto correct changed race to racism which made everything not make sense.
