It can be hard to understand how hurtful the use of slurs can be if you've never been part of a minority group that's often dehumanized by such language, but I hope you can eventually learn how to empathize with people whose life situation is different from yours.
Or if you are part of a minority group but haven't been harassed with slurs, I don't wish for you to become the target of such insults, but I hope you can come to understand why certain people might be more sensitive to such language than you are.
