I made my gamer tag as Knee Grow just because it sounds like the racial slur.
This seems a little off putting towards black people right?
I just want them to know I'm always laughing at their expense.
You're laughing at the expense of people just existing and being born who they are. You really shouldn't inflame people online or in person with your racist language.
Just because they're black doesn't make them God's gift to music.
No, but it doesn't make them any lesser than other races either. Instead of using slurs to describe black people, why not just call them black people or by their birth given name? This is how you would treat anyone else right.
