That's strange - I thought that you finally realized how wrong you were with your past prejudical thinking and was now willing to accept others who may look different from you when you recently changed your username by covering up the old "N-word" racial epithet in your username with asterisks but it seems that you're just afraid of being labeled a racist whenever people see your old username "THERES NIGGER IN THIS BLOCKCHAIN".

You can't hide from your past. There will always be people who will remember it. All you can do is change your old ways if you want things for the better in the future.
