bro these kinda accidents are weird i'm not american but it's so weird when someone clearly says it bu accident and doesn't mean or care about the actual meaning.
the word is used on the daily in america by black people and especially if u listen to rap ur gonna have this word in ur head since black people refer ro eachother with this word so it's gonna have that meaning in ur head (calling another guy or talking to him) and hiko probably accidentally said it in that context.
i don't think he's racist u know 😅 was wrong to say it but i explained above why it could happen.
i might be wrong but this what i think about it, but again i'm not american and i'm not educated on this matter or lived through racism so i might be just ignorant
