I know you're not, I understand your point

"And why do we have to be aware all the time about American culture?"

I think artist should be aware of the culture of their targeted audience
GD is clearly influenced by african-american culture, wants to be big in the US but seems to be impervious to some of it's aspect... that's just weird to me

I would give him a free pass if it was the first time, if he was ignorant and actually apologized to the people who were hurt but it's not the first time. That's my main issue really.
